Message:

Added Histogram::extendMissingBins() to generalize superpositions.

• extended unit tests on Histogram::operator..=() to also test superposition of both larger and smaller histograms.
• unit test function superposeOtherHistogram_Test() now checks whether the correct amount of bins have been added instead of thrown AssertFailure.
• removed asserts in superposeOtherHistogram().
