Simple data test incorporating FOC-related libraries

This example verifies various transforms libraries used in motor-control applications, specifically as a building block of Field-Oriented Control (FOC) motor design.

It demonstrates how to run Clarke, Park, Inverse Park transforms and space-vector generation (SVGEN). This test tries to mimic a conventional workflow of passing current values into Clarke transform, then Park, then Inverse Park (PI controllers are neglected here but should exist for both open and closed-loop design) and finally passing to SVGEN to generate the three-phase ABC values.

The test uses an arbitrary phasor angle that feeds into park/ipark, as opposed to an angle generation module required by an actual FOC design.

The test vector then compares the PARK, SVGEN results to ensure the integrity of the library.
