A compressing tool for ctrip/Taocan project

/**
* @namespace
* @fileOverview 
	It will provide a bunch of functions for you to complete the source control task in tfs.
* @author deathsteps
* @email lovely_dreamer@126.com
* @version 0.1
* @date 2013-4-17
* @example
	First you should set the path of the tf command tool by calling setEnv.
	eg. xx.setEnv(path);
	Then use the function, of which the name is the same with target command, to complete the target job.
	eg. xx.checkin(path, opts, callback);
	opts is a dictionary for the command parameters
	callback will be execute when the command finished
