Should be reviewed with: https://github.com/GPII/windows/pull/46

* Removes "datatype" entries from NP sets to be specified in the options block of a solutions entry
* Cleanup of the transformations in relation to the above, including changing the windows cursor entries to use the quantise transformation as opposed to the previous nested condition/op combo
