Get rotation angle from affine transform matrix

[softmarshmallow]

I’m very glad to use this amazing package for my project.
though, im having some trouble applying this package for my specific use - getting the rotation angle from the affine matrix array data.

Is there any existing function for extracting the rotation angle from givven affine transform matrix?

Hi,
This request is related to #2 issue, basically you can convert any transformation matrix to a triple (translate, scale, rotate) applying some formulas.
Unfortunately this feature is not available yet.

#88 releases a new function (decomposeTSR( that solves this issue
