ensure that angdiff returns a scalar for scalar args #89

fix the problem with angdiff, ndarray output for two scalar inputs. Issue #81. Also updated the tests. Note that the equality tests from unittest and numpy.test consider that a single element array is equal to a scalar. Now added explicit tests for type of result.
