/*
Function LoadFile is used to load a workspace file, draw the corresponding
grid and initialize such values as workspace size and the initial goal.
It expects the name of the workspace file or NULL.  If NULL is sent,
the function will prompt the user for the name of the workspace file.
There is no return value.  The program will terminate with an error
message if the file cannot be opened or if memory could not be allocated
for some workspace variables.
