Detailed Description

An implementation of block vectors based on the vector class implemented in TrilinosWrappers. While the base class provides for most of the interface, this class handles the actual allocation of vectors and provides functions that are specific to the underlying vector type.

The model of distribution of data is such that each of the blocks is distributed across all MPI processes named in the MPI communicator. I.e. we don't just distribute the whole vector, but each component. In the constructors and reinit() functions, one therefore not only has to specify the sizes of the individual blocks, but also the number of elements of each of these blocks to be stored on the local process.
