 Secondly, it also implements two different type of block arrays that follow the `AbstractBlockArray` interface. The type `BlockArray` stores each block contiguously while the type `PseudoBlockArray` stores the full matrix contiguously. This means that `BlockArray` supports fast non copying extraction and insertion of blocks while `PseudoBlockArray` supports fast access to the full matrix to use in in for example a linear solver.
