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

[akmon]

Thnks for version 0.05, but I still get a restart on my phisical unit when I press [Num], [Plot] or [View] and then option "Add or edit variable"
However, on my virtual calculator it works well. Could be there is some old files from the earlier version on my phisical calculator that corrupts the system?
And is there an option for solving system of equations "on the go" using your engine, for just inserting the equations without defining the variables previously?. The variables will be created automatically in the solver menu ([Num]).
