User's registered events

[guptaaditya13]

To view the list of events that user is registered in. We need to implement it twice.
A separate URL where whole list will be displayed (i.e. if there is a group event then group name and all team mates will also be displayed) along with controller and model has to be developed.
After the user is logged in, the response only contains the information about the user, we need to send the registered events at that time along with all other info.
