Improving Series Expansions

Currently, SymPy has a well-established series package in sympy/series.py. The goal of this project would be to improve the existing series package, and introduce other optimizable functionality and algorithms in the module. I would like to unify the various existing series expansions, and plan to give it a concrete structure for further development and improvement. The aim of this project would be to -:

1.) Implement more operations and improve the existing Formal Power Series methods and classes.

2.) Ring implementation of Formal Power, Laurent and Puiseux Series to make rs_series() the ultimate series function.

3.) Improving and optimizing existing limit algorithms.

4.) Unifying all the existing series expansions under one class base.
