 A block array is a partition of an array into blocks or subarrays, see [wikipedia](https://en.wikipedia.org/wiki/Block_matrix) for a more extensive description. This package has two purposes. Firstly, it defines an interface for an `AbstractBlockArray` block arrays that can be shared among types representing different types of block arrays. The advantage to this is that it provides a consistent API for block arrays.
