Need to understand something

1. This will likely cause LC tests to fail, as the fix only fixes one of the two test functions that were failing

2. We should probably add a test in LC that tests the MSE observer just as we did with the min max observer already done

3. The failure illustrates the issue that the MSE observer raises an error when it is used to quantize integer values. While tests may pass, there may be other circumstances where we want to quantize values which are integers. Adding integer quantization support is relatively quick and would be a nice follow up, but doesn't have to be done now

Good catch! Will do.
