The Add devices module for megawake
Importing this module while developing megawake allows megawake to:
* Launch the window that asks user for information about the device they want to save
* Access Defined Exception classes in this module for later use in other programs or even in megawake itself
* Append new items at the end of the saved devices list (CSV File)
License:
A module for adding new devices to the CSV file megawake uses to store the list of saved devices.
