The XML text values reader now implements two interfaces, one for
filtering the file based on attributes, another for filtering the file
based on test depth.
Moved the TestDepth enum into the API. Added package info in a few
packages missing it.
Removed the ParametersBuilder interface.
Added an interface for querying for the values to be used when
generating test parameters. Added an implementation of this interface
for querying XML files. Sorted test classes.
Removed the model package from the tests path, and moved the classes
there to the folder's parent.
