FWRT: Upgrading to 0.3 version

Features added
- Adding support for multiple managers
	Earlier code was designed assuming each individual user
	would be having at max one manager. This might not work when
	there are more that one manager.

	To solve this scenario, logic of team is in place now.

	1. Team is a composed of one or more users.
	2. While user creation and his/her team and his/her position
	   in it is given.
	3. Any user in her team with higher position than her would
	   be her manager or managers.
	4. A user can exist in more than one team.
