Created tag drjava-beta-20070803-2106

PLT Utilities updates. LambdaUtil: instanceof predicate, partial function conversion; IterUtil: added a contains test; Relation, HashRelation: added these, modeling sets of pairs with map-like indexing; CollectUtil: convenience methods to access UnionSet, etc., and ComposedMap - empty list, etc., methods - convert an option to a set - added partialFunctionClosure; Tuples: fixed equals and hashcode methods to check for null, added some handy methods to Option

Added classes for Set at Map composition. Added a CollectUtil class. Added LambdaUtil.bind methods for Predicates, and IterUtil.run methods for Runnables.

Fixed compiler warnings/errors in PLT involving casting that only came up under javac 6.

Override NoCompilerAvailable's toString() so that the GUI now displays
"None" when no compiler can be found. Previously, it used the default
toString(), of the form "NoCompilerAvaulable@#####"

Changed:
M NoCompilerAvailable.java

Removed Java 1.6 compiler check from JDKToolsLibrary.java; this is an improvement of revision 4236

Added Java 1.6 compiler check into Javac160Compiler.java; this is an improvement of revision 4228.

Added a diagonalizing version of CartesianIterator and utility methods; added an isInfinite() method to SizedIterable and improved support/documentation for infinite iterables; moved tuple getter lambdas from IterUtil to the respective tuple classes; misc iter package cleanup; fixed javadoc errors.

Added CartesianIterable and a handful of IterUtil.cross() methods for computing cartesian products. Added a couple of useful lambdas to LambdaUtil.
