/**
* <tt>Criteria</tt> is a simplified API for retrieving objects
* by composing <tt>Expression</tt> objects. This is a very
* convenient approach for functionality like "search" screens
* where there is a variable number of conditions to be placed
* upon the result set.<br>
* <br>
* In the current implementation, conditions may only be placed
* upon properties of the class being retrieved (and its
* components). Hibernate's query language is much more general
* and should be used for non-simple cases.

* <i>This is an experimental API</i>
