CLaygo is a simple wrapper class designed to encapsulate all C
function calls in a single class. It replaces LayGO API functions
starting with the lgo_ prefix with static member functions with the same
name but without the prefix. For instance, the LayGO API function lgo_Open()
is replaced by CLaygo::Open().
CLaygo is primarily intended for use by the other classes rather than
for direct use by application programs.
