Holds real data, container type and constraint for symbolic name read from persistence.
A symbolic name is a name that represents a certain set of data, usually a file, and the type of data, such as cedar, netcdf, hdf, etc... Associated with this symbolic name during run time is the constraint associated with the name.
The symbolic name is looked up in persistence, such as a MySQL database, a file, or even in memory. The information retrieved from the persistent source is saved in the BESFileContainer and is used to execute the request from the client.
