// Description:
// e32test\buffer\t_readar.cpp
// Overview:
// Test the CArrayFixFlat, CArrayPakFlat, CArrayVarFlat classes.
// API Information:
// CArrayFixFlat, CArrayPakFlat, CArrayVarFlat.
// Details:
// - Create an array of fixed length objects contained within a flat 
// dynamic buffer, append some elements onto the end of the array, 
// sort the array into key sequence, check the number of elements 
// in the array is as expected and read all of elements. Check 
// whether the heap has been corrupted.
// - Create an array of variable length objects implemented using a 
// flat dynamic buffer, append some elements onto the end of the 
// array, sort the array into key sequence, check the number of elements 
// in the array is as expected and read all of elements. Check whether 
// the heap has been corrupted.
// - Create an array of variable length objects packed into a flat buffer, 
// append some elements onto the end of the array, sort the array into 
// key sequence and check the number of elements held in the array is 
// as expected. Read all array elements. Check whether the heap has been 
// corrupted.
// - Check whether the heap has been corrupted by any of the tests.
// Platforms/Drives/Compatibility:
