Definitions:

All memory device instances are of a specific subclass of Device whose constructor provides the enumerated value of kind defined as follows:

`Data`	Used for database data (disk or memory)
`DiskCache`	Used for the disk cache
`TransactionLog`	Used for the transaction log
`AsyncBuffer`	Used as the asynchronous buffer for eXtremeDB High Availability applications
`PipeBuffer`	Used as the pipe buffer for eXtremeDB Transaction Logging applications
