/*
DISCLAIMER functionality
    
This functionality consists in displaying a modal confirmation box before clicking a link, button or submitting a form
For this functionality to be avaible you need to have a DIV with ID=disclaimerBox (this div will contain the disclaimer text) 
To display and alternate container page decorate your element with data-license-id="ID", where ID is the id of page that contains the disclaimer

Disclaimer for links and buttons
-> links need to be decorated with data-disclaimer='true'
Disclaimer for forms without validation:
-> needs to be decorated with data-disclaimer='true'
Disclaimer for forms with validation:
-> In the validation function you need to add the following code
        
showDisclaimer(FORM);    
return false;
        
where FORM is the current form.
This will instruct the code to display the validation dialog box
