Computes mesh edge length regularization loss averaged across all meshes
in a batch. Each edge contributes equally to the final loss, regardless of
numbers of edges per mesh in the batch by weighting each mesh with the
in a batch. Each mesh contributes equally to the final loss, regardless of
the number of edges per mesh in the batch by weighting each mesh with the
inverse number of edges. For example, if mesh 3 (out of N) has only E=4
edges, then the loss for each edge in mesh 3 should be multiplied by 1/E to
contribute to the final loss.
