	 *  mshop/coupon/manager/name = Mymanager
	 *
	 * The value is the last part of your own class name and it's case sensitive,
	 * so take care that the configuration value is exactly named like the last
	 * part of the class name.
	 *
	 * The allowed characters of the class name are A-Z, a-z and 0-9. No other
	 * characters are possible! You should always start the last part of the class
	 * name with an upper case character and continue only with lower case characters
	 * or numbers. Avoid chamel case names like "MyManager"!
