Polynomials

I have forked a new branch 'polynomials' from the master branch. With this package it is possible, next to the original camera orientation method, to use polynomials for particle mapping. The polynomial method works best if multi planes are used for the calibration. Calibrating with  a 3D-body  is also possible. However the user must be aware that for regions without calibration information, the accuracy is unreliable.
In the coming weeks, a new test folder will be added with images and parameter lists for testing/demonstrating the functionality of the package.
