[Maxima] More functions for pw.

[Richard Hennessy]

Does anyone have an opinion whether I should create a Fourier series command for piecewise functions?  I haven't tested the fourie 
package recently but when I last checked it did not work for piecewise functions.  I was thinking

pwfourier(pw(L,x),x)

a(0)=...
a(n) = ...
b(n) = ...

and

pwfourier_transform(pw(L,x),x)
-> some complicated function.

I already have written the code for it.
