Issue DM-3375: Test shear bias vs. CModel region.nGrowFootprint
One piece of how the CModel code chooses its fit region size is via nGrowFootprint, which is used to grow the original detection Footprint. We should test how changing this parameter affects the _m_ and _c_ shear biases between input and recovered shear. They should decrease for larger nGrowFootprint values, and eventually plateau. We want to find the point where this happens, and see how the parameter affects both the fit region area and the shear biases before this threshold. It may be necessary to make a small modification to the CModel code to output the fit region area to complete this test.
