Detailed Description
Fixture class for second-order remap tests.
Here we consider a piecewise linear field on a 2D cartesian grid with:
f(x,y) = |c * x, if (x < r). |c * (x - r) otherwise. given c > 0 and 0 < r < 1.
f(x,y) / : / / : / / : / / [0] : / [1] / : / ---------—:---— 0 r 1 Notice that we would obtain smoothed field values near 'r' with a global remap since the field gradient would be smoothed in that region. However, we should obtain a perfect remap with a clear field discontinuity using a second-order part-by-part remap, since the computed gradient near 'r' is distinct for each part.

Setup each test-case.
It creates both source and target meshes, then computes and assigns a density field on source mesh, then creates parts by picking entities within (0.0,0.0) and (0.6,1.0).
