class Launchy::Application
Application
is the base class of all the application types that launchy may invoke. It essentially defines the public api of the launchy system.
Every class that inherits from Application
must define:
1. A constructor taking no parameters 2. An instance method ‘open’ taking a string or URI as the first parameter and a hash as the second 3. A class method ‘handles?’ that takes a String and returns true if that class can handle the input.
