  • Added module fourier in sympy.series
  • Added SeqFormula class, that knows how to generate coefficients based on
    a formula
  • Added FourierSeries Class,
    This Class represents a fourier series expansion.
    Contains methods for getting the general representation of series
    and for getting the first n terms.
  • Added fourier_series function.
    It is a wrapper that returns the first n terms of a series or an
    infinite generator of terms

I have placed everything in a single file. I think it can be structured better.

May close #9077

I will be working this summer, on improving the series infrastructure. Once I get it in. It will be better to implement it using the new infrastructure. This was made when I was working on my proposal. Not very well implemented. Details.
