Speed up solvers module using SymEngine

[Shekhar Rajak]

Hello all,

This is regarding improving the performance of solvers module (mostly solveset). Since the last few months, I am working on making the Ruby and Python code faster. I came to know about Cython and other good ways to write C extension for Python code to improve the performance. 

When we run the solvers module test cases, we can see that few cases take a really long time (some of them are skipped, because of this only).

I see that SymEngine is really powerful and can boost the solvers module performance significantly. I am impressed with symengine.py and PRs like https://github.com/sympy/sympy/pull/11679 ,https://github.com/sympy/sympy/pull/11676, .. 

So I think, we should use SymEngine.py  in solvers module.

I would love to work on this idea as well.  I believe, this idea must be added in GSoC 2019 - solvers module idea-list . 

What do you guys think?

I did not realize that performance was a big concern in the solvers.
What are the sorts of things that are slow? The main one I am aware of
is solving systems of polynomials because of the Groebner basis
algorithm.
