Example 1: test mesh edges and boundary faces for negative coupling coefficients.

The objective is to use the negative_aij / rivara command that first identifies elements that have negative coupling coefficents, and then proceeds with a rivara boundary refinement to reduce or eliminate the negative couplings.

The output consists of one gmv file.
