/*
 DirTag Class v0.3
 Created by: Valentin Schmidt
	
 Clone of FlashTag Class by Mike Chambers and Christian Cantrell
	
 Generates a browser-specific Director Shockwave tag. Create a new instance, set whatever
 properties you need, then call either toString() to get the tag as a string, or call write() 
 to write the tag out.
 
 v0.4 by Emmanuel Beuque
 Adds parameters and methods to set swRemote and stretch attributes of the Shockwave tag
 
 v0.5 by Emmanuel Beuque
 Takes care of dirVars passed as strings by using ' to define sw param and 
 by replacing the single quote char with '"&numToChar(39)&"' in the OBJECT or EMBED tag
 using value in Director will restore the single quote char.
