When making libraries with `make libs`, recommended compilation and link flags for the program to use surfgen evaluation libraries
will be printed out.   Two shell scripts, one for bash/sh one for csh/tcsh, will also be created in the `bin` directory that can be
sourced to set these environment variables and adjust stack size settings.
PDF documentations now distributed with the repository.
A critical point search program `findmin` is added to the utilities.
This program can be used to search for minima, saddle points, or conical intersections on the fit surface.
More documentations for utility programs, along with installation scripts for each of them
