Beam Project GUI

Allows the user to input forces, calculates deflections and plot beam with configurations.

This is the first version of my project. It consists of 5 functions and an image.
It is developed by me, and a fellow student, credited in the main file beamProject. One of the functions is developed by Robert Cummings and downloaded from the File Exchange.
The way I solved it is with the use of global variables. In future versions, I will get rid of them. If you have ideas to how to get rid of them, please let me know.
