Release Name: 0.2.0

Notes:
= Lsof
Lsof has some utility functions that allow you to manage processes using the unix lsof command.
Functions include getting the pid and killing a process that listens on a particular port.

== Usage
  Lsof.running?(6666) # returns true if there is the process that listens on port 6666
  Lsof.kill(6666) # kill the processes that listens on port 6666
  Lsof.listener_pids(6666) # returns the process ids for the process that listens on port 6666



Changes:
- Handles multiple processes listening to the pid
- Changed Lsof.listener_pid to Lsof.listener_pids
