The test file includes a simple independent implementation of
vector rotation. Each of the following sensor_align_e types are
tested:
* CW0_DEG
* CW90_DEG
* CW180_DEG
* CW270_DEG
* CW0_DEG_FLIP
* CW90_DEG_FLIP
* CW180_DEG_FLIP
* CW270_DEG_FLIP
For each test, three unit vectors and a random vector are tested.
* {1, 0, 0}
* {0, 1, 0}
* {0, 0, 1}
* {R, R, R} (where R is a random number)
The vector under test is rotated using the functions defined in the
test file. The output of the test function is compared to the
output of the sensorsAlign() function. The outputs match for all
test conditions.
