Changes to pool access classes

Browse Source 
1. PoolRawAccessHelper is more robust now and has better error handling
2. PoolRawAccess: Removed an unneeded constructor value, moved serialize
further to the top. Added new returnvalues and more precise error
handling for read() call
3. DataSet: Made MAX Number of data pool entries public so it can be
used by pool raw access error handling
