Mainly changes to get redirection of stdout to work.
Now the defaults for overloaded functions are setup before anything else, and
the the Overloading functions count the number of times they are called
and don't allow the thing to be overloaded more than twice - once for the
default, and once for people actually wanting to overload it.
Redirection now works - output is put into files like CCTK_Proc<x> where x is the
process number.
