Detailed Description

Class referencing a DataLayout object, and abstracting the interactions for DataSource.

Only the constructor is meant to be used by code outside of DataSource. The default constructor holds no data. Do not change the underlying DataLayout until the DataLayoutChunk is destroyed. This is usually a trivial requirement, as DataSource objects (which hold DataLayoutChunk objects) only live briefly for the purpose of calling createRecord().
