The TPZAnalysis class and its attributes

In order to perform a finite element analysis using a given computational mesh, the following steps need to be performed

• The equations need to renumbered to optimize the bandwidth
• The storage format of the global matrix needs to be choosen
• The system resolution procedure needs to be choosen (e.g. direct solver, iterative solver, preconditioner)
• The postprocessing variables and output file format needs to be specified

These steps are coordinated by the TPZAnalysis class
