Utilities for Mezzanine sites

1. Install via pip: pip install mezzy
2. Add to "mezzy" to INSTALLED_APPS (if using the template tags)

Found in mezzy.utils

• admin mixins to create "nested" inline admin experiences
• forms mixins for more accessible and user-friendly forms
• models abstract model classes for common inline patterns
• tests TestCase mixin for class-based and function-based views

mezzy_tags provides the following:

• microtemplate: Filter that parses certain variables in the value param. It can be used to allow some templating capabilities in admin fields. Default template tokens can be found in mezzy.defaults.
• load_theme: Tag that adds the SiteConfiguration to the context. It also uses the request object as cache to avoid some DB hits.
• clean: Filter that removes HTML tags and attributes that aren't allowed for Mezzanine by default, even if the user has disabled filtering.
