arctan2 not returns positive results for negative angles sometimes. The fix corrects the angle depending on sign of input.
Need to make more for the other fields
Safe versions of atan2 and log that can handle the limits used in the prism codes (log(0) and correct the sign of tangents).

gxy, gxz and gyz have a singularity in certain plains around the prism. They fall on the vertices of the prism. |
Weird behavior and it seems to happen with all cross components

The cross components all fail on the edges of the prism. Will add an if for that case and add a dummy value to account for it.
The cross-components of the prism gravity gradient were failing on the corners of the prism in one of the faces. Put a check if on that face, then move the point some percentage of the prism dimensions.

There was also a problem in the cross components with the log functions. If the the point is aligned with the corner, a log(0) was being evaluated as depending on which size of the prism you are in. |

The problem was actually in the atan2 function:
The fix was to wrap atan2 and fix the result to fall where I want it to.
