	Requires:	ActionScript v. 2.0				
	Date:		April 25, 2006			
	Contact:	admin@flashmx.us				
	Created by:	Nikolay Shishenkov				
	==============================					
	Idea: this class has 1 goal to allow you to verify email address string by basic email characteristics					
	it is based on the email standards information that can be found here:					
	http://www.remote.org/jochen/mail/info/chars.html					
	==============================					
	Usage:					
	//=> |START| copy from this line					
	//={ Boolean => email_validator.validate(String); }=					
	//Import class - in this example the class is located ubder the folder "classes" (relative to the project's FLA location)					
	import classes.EmailValidator;					
	//Create the validator object:					
	var email_validator	= new EmailValidator();				
	trace(email_validator.validate("admin@flashmx.us"));		// will return true			
	trace(email_validator.validate("admin#@flashmx.us"));		// will return false - because the string contains invalid character(#)			
	trace(email_validator.validate("admin@flashmx.tooLong"));	// will return false - because the domain name is invalid				
	//... basicly it will return true ONLY if the email is complaint to the standard email address requirements					
	//= final line to copy =| END |
