Detailed Description

A utility integrator (much like NPTxyz) but which keeps the relative scaling of x & y fixed.

The z-axis can float separately from the x & y axes. There is no known conserved quantity for this integrator, but we still compute the equivalent quantity from a fully flexible constant pressure integrator.
