    ECMA Section:       15.5.2 The String Constructor
            			15.5.2.1 new String(value)
			            15.5.2.2 new String()

    Description:	When String is called as part of a new expression, it
                    is a constructor; it initializes the newly constructed
                    object.

        			- The prototype property of the newly constructed
		        	object is set to the original String prototype object,
		        	the one that is the intial value of String.prototype
        			- The internal [[Class]] property of the object is "String"
        			- The value of the object is ToString(value).
        			- If no value is specified, its value is the empty string.
