Issue with triangles fixed

Now they give the right electric field.

I have to change 2DCyl.

However, there was some insonsistency between the change of coordinates in phy2log and the Jacobian for the K matrix. I fixed it putting a transpose() in phy2log, but I don't like that solution.

I need to review the basic procedure of phy2log.
