Detailed Description

This class extends the base class to implement an array of Trilinos sparsity patterns that can be used to initialize Trilinos block sparse matrices that can be distributed among different processors. It is used in the same way as the BlockSparsityPattern except that it builds upon the TrilinosWrappers::SparsityPattern instead of the SparsityPattern.

This class is has properties of the "dynamic" type of Sparsity patterns (in the sense that it can extend the memory if too little elements were allocated), but otherwise is more like the basic deal.II SparsityPattern (in the sense that the method compress() needs to be called before the pattern can be used).

This class is used in step-32.
