  Modified files:
    octopus/src          math.F90 Makefile.am 
  Added files:
    octopus/src          math_cg_inc.F90 
  Log:
  Added a procecudre to the math module (in file math_cg_inc.F90) that
  solves a general Ax=b problem through the conjugate gradients. In fact,
  two procedures with a common interface, either for symmetric or
  non-symmetric A. The form of A is passed through an interface.
  
  Essentially, it is the Numerical Recipe without the possibility of using
  a preconditioner. This could be easily added.
