Support for case sensitivity in variable names #85

Originally reported on Google Code with ID 23

I tried to use SpeedCrunch to calculate the final result in physics
problems, but since there could easily be both small t and capital T or
small m and capital M in one formula it is now impossible to first define
all the variables and then use them in the final formula since defining M
overwrites value of m for instance.

I would rather have submitted this issue as enhancement, but I can't figure out where
I had to specify that

Hi voxiac,

Thanks for the idea.

As for enhancement, just chane Type-Defect in the label to Type-Enhancement (which
I'm doing right now)

I agree, variable names should be case sensitive. Accepting the sugestion, thank you.

Fixed in trunk, will be available in 0.8

Just noticed only one of the variables is stored in the settings and loaded back from
history. I'll fix this later, marking as Started.

In trunk, it is now possible to define variables "x" and "X", for instance. It is
also possible to define variables "PI", "Pi", "ANS", Ans" and so on. Only "pi" and
"ans" are reserved now. The only remaining issue happens when saving the settings:
if
variables "a" and "A" are defined, only one of them is going to be saved. For
portability reasons, keys cannot be case sensitive since Windows registry is not. So
we would have to take another path on this. I'll leave it like this for now, since
it
allows to use case sensitive variables in a session, and that was the issue. Marking
as "Fixed" and creating a new issue regarding the saving to settings problem.
