:param Flask app:
The Flask app (or Blueprint) to wrap.
:param \**configuration:
Configuration options that define in what way a :any:`MicronMethod`
that is created using this Micron instance must behave. These
configuration options can be overridden by method-specific
configuration options, defined in the ``@micron.method()``
decorator.
Example::
from flask import Flask
from flask_micron import Micron
app = Flask(__name__)
micron = Micron(app)
@micron.method()
def hello():
