Segmental beam properties

[JesseBonanno]

Would be good to try implement a way to specifiy different beam properties for different spans.

Would involve creating the functions:

• beam.add_segment (adds a new beam property segment)
• beam.reset_beam_properites (return beam to having single E, I, A values)

Would involve modifying:

• beam.analyse
• beam._draw_beam_schematic

Ideally implementation would just be to have beam properties defined as piecewise function, and then consider them when creating the equations in beam.analyse()

Hey Jesse, fantastic tool! Thank you! Well done and perfectly documented. Any chance you find the time to implement the segmental beam properties?
