// This must be an incredibly pointless file! But it does allow testing of the basic plugin structure.

// Each import file has an identifier which must be the same for:
//		a) This file name - add '_class.php' to get the file name
//		b) The array index of certain variables
// Array element key defines the function prefix and the class name; value is displayed in drop-down selection box
