// Description: This file contains the class definition for FileDatastore.
// FileDatastore is a concrete subclas of FE_Datastore. A FileDatastore 
// object is used in the program to store/restore the geometry and state 
// information in a modeler at a particular instance in the analysis. The
// information is stored in text files.
