Public Member function Details:
 void add(const char* name, int line, int out_start, int out_end, int diff)

Adds a map at the given line. out_{start,end} define the start and past-the-end markers for the macro in the output file. diff defines the signed difference to add to the pos.

See Also:
map(int, int)

 int map(int line, int col)

Applies added maps to the given column number. The differentials of the various macros are applied in turn, and the final column position is returned. Returns -1 if col is inside a macro

 void clear()

Clears the map. Should be called at the very start of processing, since the map is stored statically and hence potentially across parser invocations.
