deliverable: stack limits

The weakest point of the A- implementation is the stupid computation of stack limits, which are always assumed to equal 25. It would be much nicer to compute the exact limit.

This improvement can be implemented by only making changes to the file emit.c. Note that "struct CODE" in the file tree.h contains a field "int visited;" which may be useful for this task.

You should hand in your assignment by making a jar file with all of the files which you have modified, and a README file describing what you have done. The jar file should be sent by e-mail, as an attachment, to your TA. Make the subject of your e-mail "CS 520 - group xx - stack limits" where xx is your group number".

A hard copy, clearly printed and labeled with your group number should be handed in at the beginning of class.
