 Default feature, no need to turn on or off keeps logs for 45 days, users who want more can 
 Items are only removed from log when source object is deleted (and replaced with a deleted entry and textual description of deleted item)
+Needs a cleaner job that periodically looks for non-existant objects that are logged
+Has to handle a scenario where there is no data for an object because in future we will likely have a purge feature or maybe a feature to turn it off and needs to accept that scenario

+DELETION
+--------
+The only way an entry is removed from the log is via deletion of the source object
+When a source object is deleted, the entire history for that object is removed from the log and a new entry is created showing the deletion and textual representation of the object
+    - The record has the object type so no need to redundently store that, just the name: "1234" for workorder 1234 or "ABC Accounting" for the client name etc

 TODO:
 1) Implement this log and routes to interact with it
 2) Implement an auto-prune job
