log_error - log errors intelligently
void log_error( string file, string message );
Whenever an error occurs during compilation, the function log_error in the master object is called with the filename that the error occurred in and the error message itself. Then, log_error is free to do what‐ ever it thinks it should do with that information. Usually this is deciding based on the filename where the error message should be logged, and then writing it to that file.
