/**
* Represents a logical not equal operation between two nodes (the `ne` query operator).
*
* This is used in queries which resemble the following:
*
* RowKey ne 'bar'
*
* In this case, the `NotEqualsNode` would be the root node, with the left and right nodes
* corresponding to the identifier `RowKey` and the constant `bar`, respectively.
*
* NOTE: This operation includes backwards compatibility for the `guid` type hint, since
* earlier versions of Azurite stored guid values in their raw string format.
