PARAMETERS:
path - Local path to the Nucleus driver files.
REMARKS:
This function is used by the application program to override the location
of the Nucleus driver files that are loaded. Normally the loader code
will look in the system Nucleus directories first, then in the 'drivers'
directory relative to the current working directory, and finally relative
to the MGL_ROOT environment variable.

RETURNS:
Pointer to the system wide PM library imports, or the internal version if none
REMARKS:
In order to support deploying new Nucleus drivers that may require updated
PM library functions, we check here to see if there is a system wide version
of the PM functions available. If so we return those functions for use with
the system wide Nucleus drivers, otherwise the compiled in version of the PM
library is used with the application local version of Nucleus.
