Possibility to call init_app

[denisdubovitskiy]

Seems like the plugin does not support deferred app initialization like other plugins do.

To avoid any cyclic imports in the app it would be great to have init_app method which takes an app as a parameter. Sometimes it's not that easy to initialize a tracer with modular layout.
The documentation has no mention about the usage with flask app factory pattern.

Example

plugins.py

tracer = FlaskTracer()

app.py

from plugins import tracer

def create_app():
    app = Flask()
    tracer.init_app(app)
    return app

Hey @pydrive

Thanks for the info. I will work on this item before we do the eventual release of the 1.0 version (already in the works ;) )
