Creating an equation library (Updated 03-FEB-2017)

[Han]

The solver portion is done and behaves much like the SOLVESYS solver. The slight difference is that the solver falls back to fsolve in the case where there are more variables than there are equations (usually infinite solutions). In this case, the non-constant initial values are ignored. If there are more equations than variables, then a least squares approach will be used.

What I am working on now is the interface. Sadly, the CHOOSE() and MSGBOX() commands are just not sufficient for what I need. Moreover, they keep switching the view back to the command line view rather than just drawing directly onto the current view.
