""" Method to initialize the Application class.
The capsulview application can be executed with command
line options (that can also be passed to the class constructor
as extra_options). From the command line, we can set the
debug level with the -d option:
* debug
* info
* warning
* error
* critical
For exemple:
>>> capsulview -d debug
The default mode is error.
From the command line we can also redirect all messages
to a graphical message box with the -r option:
>>> capsulview -r
Parameters
----------
extra_options: list (optional)
some additional options that are not passed through the command
line.
