import mod, please note: i changed the lookUpType field 'code' to 'lookUpCode' and did the same for the LookUp document...
did this because we had two different names going 'code' and 'codeType'

Also, am noticing the following anomalie: dtype rejects a model for having a null value in a non-required field.
This was happening for 'status' on Contactables and on 'status' and 'duration' on Job...
I got around this temporarily by making those fields requiredforadd
