Adds a method `DebugPanel.init_app()` that gets called from `DebugToolbar.init_app()`. This allows DebugPanels to register their own routes, and do setup work that should go across requests (as opposed to per-request setup) and needs access to the Flask `app`-object.
Flask Debug-toolbar
===================
This is a port of the excellent `django-debug-toolbar <https://github.com/jazzband/django-debug-toolbar>`_
for Flask applications.

Installation
------------
Installing is simple with pip::
$ pip install flask-debugtoolbar
Usage
-----
Setting up the debug toolbar is simple::
from flask import Flask
from flask_debugtoolbar import DebugToolbarExtension
app = Flask(__name__)
# the toolbar is only enabled in debug mode:
app.debug = True
# set a 'SECRET_KEY' to enable the Flask session cookies
app.config['SECRET_KEY'] = '<replace with a secret key>'
toolbar = DebugToolbarExtension(app)
The toolbar will automatically be injected into Jinja templates when debug mode is on.
In production, setting ``app.debug = False`` will disable the toolbar.
See the `documentation`_ for more information.
