This routine creates a new item of data that can be read and written. Pass in the data’s full name for searching, the type(s) of the data for accessing, and whether the data can be written to. For each data type you support, pass in a read accessor function and a write accessor function if necessary. Pass NULL for data types you do not support or write accessors if you are read-only.

You are returned a dataref for the new item of data created. You can use this dataref to unregister your data later or read or write from it.
