-- Verified now to be correct at runtime
-- UnitTest covers this
-- createTypeDefault now takes a Type, not a Class, so that parameterized classes can have their parameter fetched in the defaults.
-- support for explicit naming of bindings (-X:name,type x)
-- support for automatic naming of bindings in lists (-X:vcf foo.vcf -X:vcf bar.vcf will generate internal names X and X2)
-- ParserEngineUnitTest expanded to cover all of the Rodbinding cases
-- RodBindingUnitTest tests all of the low-level accessors
-- Parsing engine throws UserExceptions when bad bindings are provided on the command line
