modified the notifications model. the sent_to is now a foreign key. now if we have a new type to be added, we can generate message and sub while creating notification. we can keep track of history using the role field in notification and task/sent_from

{% extends 'base.html' %}
{% block content %}
    Form here
    <form action="" method="post">
    {{form.as_table}}
    <input type="submit" value="submit">
    </form>
{% endblock %}
