Add support for zero parameter methods in conditions for PojoEvaluator. 
Parsing support is disabled by default but can be enabled using
forCondition(..., true).

Add a PojoOrdering class that supports parsing SQL like order by
clauses.  Once parsed, the class supports retrieving a comparator that
compares objects reflectively based on the fields supplied in the order
by clause.  Additionally, a sort() helper method is available that will
sort a list based on the order by clause.
