Method to update points for CIIMS using arcpy Data Access Cursor.  Note
that the DA cursor is not recognized by the IDE because it does not
include the typical python wrappers - it works when tested in the Arc
python command line, and should work when run against the compiler.
Because of this, PyDev and potentially other environments will show unit
test errors when da methods are called.  

Need to include an insert cursor (or other insert method) to add new
records, and a delete method when records are removed.
