//-------------------------------------------------------------------
// VERSIONS :
// 1.0  : Initial release
// 1.1  : +	: Added unit in the constructor
//	  + : Now Positions start @ (1,1).. then the first image @top-left of a page is (1,1)
//	  + : Added in the description of a label :
//		font-size	: defaut char size (can be changed by calling Set_Char_Size(xx);
//		paper-size	: Size of the paper for this sheet (thanx to Al Canton)
//		metric		: type of unit used in this description
//				  You can define your label properties in inches by setting metric to 'in'
//				  and printing in millimiter by setting unit to 'mm' in constructor.
//	  Added some labels :
//	        5160, 5161, 5162, 5163,5164 : thanx to Al Canton : acanton@adams-blake.com
//		8600 						: thanx to Kunal Walia : kunal@u.washington.edu
//	  + : Added 3mm to the position of labels to avoid errors
