Detailed Description

PartitionedRectangleMesher meshes the rectangle $ \left[a_x, b_x\right] \otimes \left[a_y, b_y\right] $ with $ n_x \otimes n_y $ elements per processor.

The rectangle is partitioned among processors, with $np_x$ equal sized subdomains in the $x$ direction and $np_y$ in the $y$ direction.
