Bugs Fixed in 3.0:
==================
+* JEXL-184: dot-ed identifiers parsing failure
* JEXL-180: Documentation - suggests using float for financials
* JEXL-171: Map access operator does not work if key name clashes with map property name
* JEXL-169: A string is wrongly identified as FloatingPointNumber
