assertion failure in tests/test_imus.py

[robcee]

running a unittest on my local machine, I ran into this assertion:

FAIL: test_kalman (skinematics.tests.test_imus.TestSequenceFunctions)

Traceback (most recent call last):

allowing that assertion to pass (modifying the test to allow for a difference of 0.2 by 1 places), I have no other errors.
