// Description:
// e32test\buffer\t_bflat.cpp
// Overview:
// Test all aspects of the CBufFlat class.
// API Information:
// CBufFlat.
// Details:
// - Test all the operations of the class and see if methods are implemented -- 
// including NewL, Reset, Size, Set Reserve, InsertL, Delete, Ptr, Read, Write and Compress.
// - Test CBufFlat constructor is as expected.
// - Insert data into the flat storage dynamic buffer and verify that InsertL method
// is as expected.
// - Delete all data in buffer using Reset() method  and check size is zero.
// - Test Ptr, Free, Size, Backptr and SetReserveL methods work as expected.
// - Insert data into the buffer, delete some data from the beginning, middle, end and
// check for data is as expected. 
// - Verify the data in the buffer before and after Compress and Read methods is as expected.
// Platforms/Drives/Compatibility:
// All 
// Assumptions/Requirement/Pre-requisites:
// Failures and causes:
// Base Port information:
