Add Python 3 as Interpreter in PyDev Eclipse Luna

When you install PyDev on Eclipse Luna, the default interpreter for python is selected as Python2 on Ubunut 14.04 machine because Python2 is the default package in Ubuntu. Lots of new features have been added to Python 3 which are not supported in Python2. So, you need to install Python 3 on Ubuntu machine if you want to use it. Also, when you type ‘Python’ on Ubuntu terminal, it selects Python 2. To select Python 3 as interpreter, you need to type ‘Python3’ on the terminal. Assuming you already installed Python 3 on your Ubunu machine (command sudo apt-get install python3 can be used to install Python3) , do the followings to add Python3 to Pydev Eclipse.
