SqlBuilder 2.0.5

SqlBuilder is a library which attempts to take the pain out of generating SQL queries within Java programs. Using one programming language (Java) to generate code for another language (i.e. SQL) is always a challenge.
There are always issues with escaping characters within string literals, getting spaces in the right place, and getting the parentheses to match up. And often, even after the code is debugged and fully tested, it is still very fragile.
The slightest change will throw things out of balance and will require another round of tweaking and testing.
SqlBuilder changes that whole scenario by wrapping the SQL syntax within very lightweight and easy to use Java objects which follow the "builder" paradigm (similar to StringBuilder).
This changes many common SQL syntactical, runtime errors into Java compile-time errors! Lets dive right in to some quick examples to to see how it all works.

Enhancements
- Add support for additional query "set operators" (EXCEPT, INTERSECT), and add support for mixed usage of said operators. Fixes 2794171 .
- Add UnaryCondition EXISTS and UNIQUE operators.
- Fix isEmpty implementation for Subquery.
- Dont put double parens around IN condition with subexpression.
