Merge pull request #600 from balabhv/vb573

More progress on recording data in iOS car ramp physics
Sample intervals greater than 1000 record data, data point count division error fixed.

Easy fix (add a boolean = false statement) to fix bug: rotating re-enables step 2 when it should be disabled after recording.
