Examine relationship between LookupUserInfo and Resource

[rhodges]

LookupUserInfo was not granted a new ID field like the other lookups since it didn't look to be used.

Now it seems it may be tied to Resource data - Do we need to:

• give LookupUserInfo an ID field
• Add FK field to Resource Model for LookupUserInfo
• Update import to assign IDs on import
• Update import to translate Resource values into LookupUserInfo IDs
• Establish a relationship between Users and LookupUserInfo
