"""A generator storing necessary parameters to simulate
geometrical EBSD patterns.
Parameters
----------
detector
Detector describing the detector-sample geometry.
phase
A phase container with a crystal structure and a space and
point group describing the allowed symmetry operations.
rotations
Unit cell rotations to simulate patterns for. The
navigation shape of the resulting simulation is determined
from the rotations' shape, with a maximum dimension of 2.
