working on encrypt function.
i believe encrypt is working.
i think pascal is all good.
encrypt should be working for scala.
Scala is pretty much done.
negatives  shifts work with scala now.
double checked symbols are working with scala.
negative shifts working in pascal now.
updated symbol stuff.

Could easily do negative shifts, but it would mess with  printing stuff
so if I really need to do it, it will be later.
Merge branch 'master' into COBOL

added COBOL work back to master.
