    Creates a drop-in SQRL element in your template pages.
    Add it to your login template to make it SQRL-aware.
    
    Usage:
    {% load sqrl %}
    {% sqrl as session_sqrl %}
    {% sqrl_login_dropin session_sqrl REDIR %}
    
    REDIR is the registered name of the page to move to once the login
    is completed. 
    
    Notes:
    The drop-in is defaulted to a max-width of 300px. Set the width
    property of the parent if you want or need it smaller. You will
    likely want to change the font-size as well in this case.
