Jan Steemann 2394cdf640 optimize away logical negation if possible 
the AST is checked for logical negations of comparison operations
if appropriate, the negation is converted into the reverse comparsion operation, e.g.

    NOT (a == b) => (a != b)
    NOT (a != b) => (a == b)
    NOT (a > b)  => (a <= b)
    NOT (a >= b) => (a < b)
    NOT (a < b)  => (a >= b)
    NOT (a <= b) => (a > b)
