Use 'neq' instead of 'df' for Boolean not-equal operation #26

As noted in #3 bug report, 'df' is a poor choice for Boolean not-equal, standing for 'different' and at risk of being confused for 'difference'. 'neq' is a unambiguous choice standing for 'not-equal' in similar fashion as already present operators: 'eq', 'leq', 'geq'.

Fixes #3.
