Cartesian to polar coordinates description

Cartesian to polar coordinates converter is an useful tool that allows you to convert your coordinates with flexibility and functionality.

Starting from 2 couple of points (names of points can be changed, as default they are A and B) this tool calculates:
- The distance between the two point
- The azimuth of the first point referred to the second, with these units: units grad, deg, d°m's" and rad
- The azimuth of the second point referred to the first, with these units: grad, deg, d°m's" and rad

To give more comfortable usage, emptiers fields are added (if users want to use them).
