	* of 2 where the first is the name of the field, and the second the value.
	* This function will modify the object that was passed to the function,
	* it will not return any value
	*
	* Example:
	* var myObject = {};
	* function(myObject, "age", 21, "gender", "male");
	*
	* Result:
	* myObject = {
	* 		'age' : 21,
	* 		'gender' : "male"
	*  }
	*
	* You can also pass an array as the first parameter, then all objects
	* in that array will have the fields set to them
	*
	* Example:
	* var myObjectArray = [{}, {}];
	* function(myObjectArray, "age", 21, "gender", "male");
	*
	* Result:
	* myObjectArray = [{
	* 		'age' : 21,
	* 		'gender' : "male"
	*  },
	*  {
	* 		'age' : 21,
	* 		'gender' : "male"
