[ldd-cart] Update definitions to fix typos/wording

Describe the issue identified Some class/attribute definitions have typos or other wording issues.

Describe the solution you'd like Recommended typos/fixes:

Map Projection Class definitions:

[x] Line 3982: Map_Projection_Lander class: Definition says "The Map_Projection class" but should say "The Map_Projection_Lander class"

Other class definitions:
[x] Line 4017: Surface_Model_Parameters class definition: To be consistent with other class definitions it should read “The Surface_Model_Parameters class describes…” instead of "This class describes"
[x] Line 2694: Cartography class definition: Extra "or" in "The Cartography class provides a description of how a 3D sphere, spheroid, or elliptical spheroid, or the celestial sphere is mapped onto a plane."
[x] Lines 4637 (Vector_Projection_X_Axis) and 4653 (Vector_Projection_Y_Axis): Definitions include "this vector defines how the axis in the mosaic is oriented in space": should the "" be there? Is that a placeholder for a word?

Attribute definitions (alphabetic order):
[x] angular_scale: Suggest definition indicates "radians/pixel" (plural) or "rad/pixel".
[x] Line 1414: bearing_reference_meridian: The value_meaning for "Magnetic" refers to the Earth only. Omit "on Earth"?
[x] Line 565: c_axis_radius: Suggest adding a period to the end of the definition.
[x] Line 652: coordinate_system_type: Suggest capitalizing "an inertial..." in the value_meaning for Inertial.
[x] Line 1332: distance_resolution: Definition says "expressed in Planar Distance Units of measure" but unit_of_measure_type is Units_of_Map_Scale. Suggest using the same language in the definition.
[x] east_bounding_coordinate: Suggest removing commented-out Terminological_Entry values if not needed.
[x] Line 1053, 1058: grid_coordinate_system_name: Very nice value_meanings. Suggest capitalizing the start of value_meaning for ARC Coordinate System and Other Grid System and making them into complete sentences.
[ ] Line 2552: local_time_scale: It is not clear from the definition how this is a "time scale".
[x] Line 583-584: longitude_direction: Suggest updating definition to use Title Case versions of permissible values instead of all-caps (e.g., POSITIVE_EAST -> Positive East) for internal consistency.
[x] Line 603: longitude_direction: Typo in value_meaning for Positive East: "bodies" -> "body's"
[x] Line 2480: look_direction: Update "theBIDR" -> "the BIDR". Please also spell out BIDR to avoid unknown acronyms.
[x] Lines 2492, 2496: look_direction: One value_meaning uses "ground-track" while the other uses "groundtrack"; resolve for consistency (should also match usage in definition).
[x] Line 996: map_projection_name: van der Grinten value_meaning refers to itself as "Vander Grinten". Capitalization and spacing should be consistent.
[x] Line 924: map_projection_name: Orthographic value_meaning states: "... a plane tangent to the earth". Suggest changing to "a plane tangent to the body" to generalize beyond the Earth.
[x] map_projection_name: Equirectangular value_meaning states: "This form is often called the Plate Carree or the Simple Cylindrical projection." Since these are not permissible values, consider clarifying that Equirectangular is the preferred term for all three.
[x] map_projection_name: Robinson value_meaning states: "Also called orthophanic." Orthophanic is not a permissible value, so consider clarifying that Robinson is the preferred term.
[x] map_projection_name: van der Grinten value_meaning states: ""conceived as a compromise between the Mercator and the Mollweide projection"", but Mollweide is not a permissible value. Consider adding a reference so readers know what it is.

[x] Line 2060: map_projection_rotation: Definition would benefit from more detail - what is this value? Why was it "included for generality" even though always 90 degrees for one particular instrument?
[ ] max_footprint_line: Definition: "size" of a footprint seems like it should require units. Or, should this be the "number" of footprints?
[ ] max_footprint_sample: Definition: "size" of a footprint seems like it should require units. Or, should this be the "number" of footprints?
[x] maximum_elevation: Definition: it isn't clear why this value applies for more projections than the minimum_elevation attribute does. Should they mach?
[ ] min_footprint_line: Definition: "size" of a footprint seems like it should require units. Or, should this be the "number" of footprints?
[ ] min_footprint_sample: Definition: "size" of a footprint seems like it should require units. Or, should this be the "number" of footprints?
[x] minimum_elevation: Definition: it isn't clear why this value applies for fewer projections than the maximum_elevation attribute does. Should they match?
[x] north_bounding_coordinate: Suggest removing commented-out Terminological_Entry values if not needed.
[ ] oblique_line_latitude: Definition: recommend explaining what "the oblique line" is.
[ ] oblique_line_longitude: Definition: recommend explaining what "the oblique line" is.
[x] oblique_proj_pole_latitude: Definition: recommend changing OBLIQUE_CYLINDRICAL to match "Oblique_Cylindrical" for consistency with specification in the Map_Projection class.
[x] oblique_proj_pole_longitude: Definition: recommend changing OBLIQUE_CYLINDRICAL to match "Oblique_Cylindrical" for consistency with specification in the Map_Projection class.
[x] oblique_proj_pole_rotation: Definition: recommend changing OBLIQUE_CYLINDRICAL to match "Oblique_Cylindrical" for consistency with specification in the Map_Projection class.
[x] oblique_proj_x_axis_vector: (1) Typos in definition: "attirubte" -> "attribute"; "makeup" -> "make up"; "90" should be deleted. (2) Recommend changing all-caps class names to Title Case for consistency with specification in the Map_Projection class (and elsewhere).
[x] oblique_proj_y_axis_vector: (1) Typos in definition: "attirubte" -> "attribute"; "makeup" -> "make up"; "90" should be deleted. (2) Recommend changing all-caps class names to Title Case for consistency with specification in the Map_Projection class (and elsewhere).
[x] oblique_proj_z_axis_vector: (1) Typos in definition: "attirubte" -> "attribute"; "makeup" -> "make up"; "90" should be deleted. (2) Recommend changing all-caps class names to Title Case for consistency with specification in the Map_Projection class (and elsewhere).
[x] projection_elevation_line: The minimum value of 1 implies that lines are one-indexed (versus zero-indexed); if so, it might be helpful to explicitly state this in the definition.
[x] reference_latitude: (1) Definition appears only to apply to the Cassini mission; check if this is true or should be generalized (i.e., for any mission using Oblique_Cylindrical). (2) Recommend changing all-caps class names to Title Case for consistency with specification in the Map_Projection class (and elsewhere).
[x] reference_longitude: (1) Definition appears only to apply to the Cassini mission; check if this is true or should be generalized (i.e., for any mission using Oblique_Cylindrical). (2) Recommend changing all-caps class names to Title Case for consistency with specification in the Map_Projection class (and elsewhere).
[x] rings_map_projection_name: Definition: Please define CIRS or remove this reference to a specific instrument, for general use.
[x] south_bounding_coordinate: Suggest removing commented-out Terminological_Entry values if not needed.
[x] spcs_zone_identifier: (1) This coordinate system seems to be specific to the U.S.; if retained, it would be helpful to specify this limitation in the definition. (2) There are only ~125 zones, so it is not clear why the user must specify four digits. Should the leading digit be optional (and minimum_characters set to 3)? If not, perhaps the definition can explain why four digits are required to aid the user.
[x] start_azimuth: Definition says this only applies to Cylindrical and Cylindrical_Perspective classes, but it is also required by the Perspective class.
[x] stop_azimuth: Definition says this only applies to Cylindrical and Cylindrical_Perspective classes, but it is also required by the Perspective class.
[x] ups_zone_identifier: It is not clear what the A, B, Y, Z values mean; more information would help users choose.
[x] utm_zone_number: UTM zones are typically 1-60, but here 0 is allowed as well as negative values down to -60. It is not clear what those values would mean. Consider updating the definition to clarify.
[x] west_bounding_coordinate: Suggest removing commented-out Terminological_Entry values if not needed.

[x] Lines 4637 (`Vector_Projection_X_Axis`) and 4653 (`Vector_Projection_Y_Axis`): Definitions include "this vector defines how the axis in the mosaic is oriented in space": should the "" be there? Is that a placeholder for a word?
