[OpenMesh] Using decimator in open mesh.

I have been having a very hard time getting usable results from the decimator tool and am wondering what I am doing wrong.

I have mostly been looking at using the "ModQuadricT". However it seems that any usage of non-binary ModQuadricT with `decimate` like shown here (https://www.graphics.rwth-aachen.de/media/openmesh_static/Documentations/Ope...) will completely remove almost all vertices since the non-binary version has `max_err_` set to DBL_MAX. I instead have to use `decimate_to`. However, even with decimate_to the end result has many overlapping triangles while the original mesh had none.

Is there a recommended way of using this tool?
