First completely working version

Represents the completely working core set of evaluation functionality. Expressions can be made, evaluated, and inspected in all the expected ways, parameters are handled like you'd expect, and test coverage is good. This doesn't represent more advanced features (such as date parsing or translation to DB queries), but it does what it says on the tin, and is ready for production use.

Functional pre-release

This release covers most of the common use cases, and represents the first build for which the library could actually be used. There are no extra features, poor test coverage, and missing functionality, but it can definitely be used in 90% of cases.
