'''
This script will install environment variables needed to by cocos2d-x. It will set these envrironment variables:
* COCOS_CONSOLE_ROOT: used to run cocos console tools, more information about cocos console tools please refer to
https://github.com/cocos2d/cocos2d-console
* NDK_ROOT: used to build android native codes
* ANDROID_SDK_ROOT: used to generate applicatoin on Android through commands
* ANT_ROOT: used to generate applicatoin on Android through commands
* COCOS_X_ROOT: path where cocos2d-x is installed
* COCOS_TEMPLATES_ROOT: path where cocos2d-x's templates are installed

On Max OS X, when start a shell, it will read these files and execute commands in sequence:

~/.bash_profile
~/.bash_login
~/.profile

And it will read only one of them. So we will add environment variable in the same sequence.
Which means that
* add environment variables into ~/.bash_profile if it exists
* otherwise it will the add environment variables into ~/.bash_login if it exists
* otherwise it will the add environment variables into ~/.profile if it exists

Will create ~/.bash_profile when none of them exist, and add environment variables into it.
