Defining templates to match sub-forms

To foster re-usability, each sub-form is associated with its own template. As an example, the Name subclass is associated with NameForm, which in turn is rendered using the property_name.html template, shown here:

    {% load static %}
    <h3>Contact Name</h3>
    <div class="row">
        <div class="col-md-4">{{ form.name_title.label_tag }}</div>
        <div class="col-md-4">{{ form.name_title }}</div>
        <div class="col-md-4">{{ form.name_title.errors }}</div>
    </div>
    <div class="row">
        <div class="col-md-4">{{ form.name_first.label_tag }}</div>
        <div class="col-md-4">{{ form.name_first }}</div>
        <div class="col-md-4">{{ form.name_first.errors }}</div>
    </div>
    <!-- other fields not shown -->

Each sub-form has its own template...
