* Orderability

* The Cypher CIP defining orderability
*
*
*
* Ascending global sort order of disjoint types:
*
*
* - MAP types
*
* - Regular map
*
*
- NODE
*
*
- RELATIONSHIP
*
*
* - LIST OF ANY?
*
*
- PATH
*
*
- POINT
*
*
- STRING
*
*
- BOOLEAN
*
*
- NUMBER
*
* - NaN values are treated as the largest numbers in orderability only (i.e. they are put after positive infinity)
*
* - VOID (i.e. the type of null)
