ISuiteBuilder
The ISuiteBuilder interface is exposed by a class that knows how to
            build a single test suite from a specified type.
            
                
Builds a single test suite from the specified type.
            
Builds a single test suite from the specified type, subject
            to a filter that decides which methods are included.
            
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.
