// Description: This file contains the class definition for 
// DomainDecompositionAnalysis. DomainDecompositionAnalysis is a subclass 
// of AnalysisAnalysis, it is used when performing a domain decomposition
// analysis. It provides methods which can be invoked by a subdomain to
// perform the numerical computations required.
