[GiNaC-devel] Derivative of conjugated is conjugated of derivative.

[Vladimir V. Kisil]

	Dear All,

  Further to my previous patch on functions derivatives, this small
  patch adds the rule 

conjugate(f)'=conjugate(f')

  to the GiNaC. The change can be seen here:

  cout << conjugate(log(z)).diff(z) << endl;
  // (before) -> z^(-1)*D[0](conjugate)(log(z))
  // (now)  -> conjugate(z)^(-1)

  Best wishes,
  Vladimir
