using libpari

[Ed Davis]

here's small demo on how you can use libpari http://pari.math.u-bordeaux.fr/
this demo show but a tiny bit of what you can do with the lib
note, some functions will only work on a real console window hence my use of $Console:Only and _Dest _Console
attached below is the libpari dll if you don't want to install Pari/gp

So, if it was me, I would change the expression parser to not solve the equation, but just do a syntax check.
If the syntax is ok, then pass the string to the library routine.

Does that make sense?
