Massive update.
Migrated calc3a to calc3p.  Now based on c++ instead of c.
FIXED: Implementation of floating point values! FINALLLY!
New version has almost completely striped the old interpreter functionality of the calc3a file.
The new calc3p file operates much more like a compiler.
Only thing thoroughly tested was print and new float datatype assigns.
**We are not using doubles anymore**

Too many changes to list here.
