ideal_ttm - construct a ideal tip-tilt mirror.
construct a ideal tip-tilt mirror. The dynamic model does not include effects of hysteresis, and uses a constant angular velocity approximation to the mirror orientation. (i.e. the mirror moves at constant angular velocity towards its commanded position until it reaches that position, and then stops).
