Purpose: Look for the home directory of the user.
Syntax: path=
PsychHomeDir([subDir])
When called without optional 'subDir' argument, the path to the
users home folder is returned. When 'subDir' is given, the
path to the subfolder 'subDir' inside the home folder
is returned - and the 'subDir' created inside that folder
if neccessary.
