Axis classes

[UlascanErsoy]

• Implemented the Axis object logic for Spatial Projection.
• Implemented some tests

class LinearSpatialAxis(BaseAxis):
    """SpatialAxis converts cartesian coordinates
    into polar coordinates (r, theta, phi)
    This is achieved by projecting the points on to an imaginary
    plane that sits directly in front of the listener at all times.
    The plane is assumed to be at unit distance, any further distance effects
    can be applied later by scaling the r in polar coordinates
