"""Web2Executable
An application that creates cross platform executables from HTML and Nodejs
web applications powered by NW.js.
This is the main module that handles all the GUI interaction and generation.
The GUI is automatically generated from the config file located in
`files/settings.cfg`.
Since the GUI is automatically generated, the settings.cfg contains many
configuration options for each element. Also, this class is set up so that
any time a user interacts with an element in the GUI, the underlying data
is modified and can be accessed via
``self.get_setting("setting_name_from_settings_cfg").value``.
Run Example:
All that is needed to run the following after running instructions in
`SETUP.md`.
$ python3.4 main.py
