* Added required files to create a snap package. Launchpad account will automate the build whenever code is committed to git repo
# What is a snap?
A snap :
* is a squashFS filesystem containing your app code and a snap.yaml file containing specific metadata. It has a read-only file-system and, once installed, a writable area.
* is self-contained. It bundles most of the libraries and run-times it needs and can be updated and reverted without affecting the rest of the system.
* is confined from the OS and other apps through security mechanisms, but can exchange content and functions with other snaps according to fine-grained policies controlled by the user and the OS defaults.
//TODO
* Try reducing the size of final snap packages by removing unnecessary packages from priming stage
