Updated LOTS of toString methods. Need to do much more work across the board now that i'm testing. Also, fixed quite a few bugs with the PackageStruct code. There are still some loading issues between Symbols and Packages and not sure how that's going to work yet. Finally, there is a classloading issue. The changes in the ReadEvalPrint.java file essentially FORCE the Java classloader to load the SpecialOperators. Need to understand better why i need to do this and what the correct scheme to accomplish this is eventually.
