[GiNaC-devel] Expand method in functions

	Dear All,

	So far we had pow(2,a+b).expand() -> pow(2,a)*pow(2,b), but
  exp(a+b).expand() -> exp(a+b). It will be also nice to have
  abs(a*b).expand() -> abs(a)*abs(b) and 
  log(a*b).expand() -> log(a) + log(b) (for positive a and b, of course). 
  Thus, I am proposing a patch for this.

  Best wishes,
  Vladimir
