ISuiteBuilder
The ISuiteBuilder interface is exposed by a class that knows how to
build a suite from one or more Types.
Build a TestSuite from type provided.
Examine the type and determine if it is suitable for
this builder to use in building a TestSuite.
Note that returning false will cause the type to be ignored
in loading the tests. If it is desired to load the suite
but label it as non-runnable, ignored, etc., then this
method must return true.
