+// Overview:
+// Test methods of CCirBuffer and CCirBuf template class.
+// API Information:
+// CCirBuffer, CCirBuf.
+// Details:
+// - Create a circular buffer, add integers to the circular buffer and check that 
+// they are added as specified.
+// - Verify Remove and Add work as expected.
+// - Check that all the added objects are removed.
+// - Create a circular buffer, add concrete data type object one, many at a time to the 
+// circular buffer and check that they are added as specified.
+// - Remove the concrete data type object one, many at a time from the circular buffer
+// and check that they are removed as expected.
+// - Check that all the added objects are removed.
+// - Create a circular buffer, add 8-bit unsigned character object one, many at a time
+// to the circular buffer and check that they are added as specified.
+// - Remove multiple 8-bit unsigned character objects from the circular buffer and 
+// check the added and removed objects are same.
+// - Create a circular buffer of unsigned integers, add single, multiple objects to the 
+// buffer and check that they are added as specified.
+// - Remove multiple objects from the circular buffer and check the added and removed 
+// objects are same.
+// - Create a circular buffer, add multiple signed integer objects to it, remove 
+// the objects and verify that the added objects are removed.
+// - Create a circular buffer, add integers to the circular buffer and check that 
+// they are added as specified.
+// - Verify Remove works as expected.
+// - Test whether the heap has been corrupted by all the tests.
