starting to sort out like/matches.  Matches is the java regex related one.  Like is the SQL related one.  But the spring .net 'like' doesn't seem to be the same as the SQL doc I found for like...

added support for long[] in stringValueOf() - plus an error reported if the type passed in is not supported

fixed some tests that will now break because int/long can be treated as boolean.  May need to change again if real numbers get the same treatment.

new tests for ternary - checking conversion of numbers to boolean and correct error when condition result not convertable to boolean

Added SuppressWarning to hide all the warnings from the poor Antlr generated code.  Code formatter also chewed on the file when saved.

TODO moved out to readme.txt which contains latest interesting issues - they should become JIRAs when the dust has settled

added support for getValue(state,desiredType) so other nodes can ask for a transform to be done on the result if necessary, rather than duplicating conversion logic all over
