Simple hash table implementation

[vmagnin]

@FortranFan

I recommend using a C function for hashing (or C++ with extern C attribute): it’s so much more straightforward given Fortran 2003 and standard interoperability.

There are hash tables in the GLib library (C language):

GLib-2.0

They should be accessible via gtk-fortran (I never tried):
