Need "equals" and "not equals" functions

[James Powell]

The DIFF function doesn’t quite work as this, as it finds changes from one JSON to another but ignoring missing elements, so to do a “not equals” one needs to do the DIFF both ways.

An actual “not equals” would both be quicker, and clearer and less prone to error.

[James Powell]

DIFF function also needs better documentation, as it is confusing as to the asymmetry between the two inputs.

Equivalent or Not Equivalent is better terminology

Added "Not Equivalent" to palletes

[James Powell]

Removed the Error terminals, as we sometime threw error on invalid JSON, and sometimes not. Could add it back later.

Improved Testing, and found cases where identical, non-valid JSON would be “Equivalent”. ALso, valid identical JSON with following “rest of string” could identify as not equivalent. Modified to properly get the next JSOn value in all cases.
