- Added last seen data to contact
- Contacts are not sorted by lastSeen
- Contact updating last seen time is handled
Built a simulation to test the contact last seen updates
CLO was timing out even if it had found the specified amount of content needed. Fixed that by exiting after the specified # of content required has been found
When doing a NodeLookup, Content Lookup or Connect operation, after sending the message, we used to wait(operation_timeout) time before checking for a result.
Now what I'm doing is waiting for 100 ms and check for a result every 100ms; I keep a count of total time waited, and only when the total time > operation_timeout do we make a timeout.
So now we can handle the response if it comes in before Operation_timeout time is finished
