/* A3 Dialog Box 1.0
/* Requires jQuery 1.3.2 
/* By Lars Michael Astrom (http://www.lars-astrom.com)
/* Copyright (c) 2010 A3 IT Solutions

/* Tested in IE7, IE8, Firefox 3.5, and Chrome 4.0
/*/

/*/
/* Implementation
/* Suggested implementation is to set options as a variable and pass it into the plug in
/* so that if the "open" command is used, you still get the options.

/* Sample implementation:
/* var dialogOptions = {
/*   autoOpen: true, 
/*   alignment: "right", 
/*   offset: 175 
/* };
/* $(document).ready(function(){ $("#Dialog").A3OptInDialog(dialogOptions); });

/* To open the dialog box with an event (such as onclick) pass "open" to the plug in:
/* $(document).ready(function(){ $("#Dialog").A3OptInDialog("open", dialogOptions); });
/*/
