Implementing transcendental equation solver for solveset #GSoC Project

[Yathartha Joshi]

I wish to work on implementing Equations solvable by LambertW (Transcendental equation solver) isssue#10006  in the solveset module.

This would be one of my major GSoC project. I am looking over the idea about how solve implements this. It uses _tsolve for handling transcendental equations.

I need help regarding understanding the way _tsolve is implemented. Also, do I need to implement _tsolve in solveset in  the similar fashion as in `solve` or any other way.
