/*!
 @brief A collection of tests (or test groups).

 A test group is a collection of id<GHTest>, that may represent a set of test case methods. 
 
 For example, if you had the following GHTestCase.

 @code
 @interface FooTest : GHTestCase {}
 - (void)testFoo;
 - (void)testBar;
 @end
 @endcode
 
 The GHTestGroup would consist of and array of GHTest, [FooTest#testFoo and FooTest#testBar], 
 each test being a target and selector pair.

 A test group may also consist of a group of groups (since GHTestGroup conforms to GHTest),
 and this might represent a GHTestSuite.
