Box Shear

Shear bias model that divides the plane into two parts: a rectangular region of arbitrary size and location and everything else. The outer and inner regions each their own constant shear level. By default, the shear bias is zero outside of the box, and .02 in both gamma1 and gamma2 within the box.

InnerGamma1 Amount of shear bias along x-y axis within the box.
InnerGamma2 Amount of shear bias 45 deg to x-y axis within the box.
OuterGamma1 Amount of shear bias along x-y axis outside of the box.
