nwjs beagle getting started app: Report 7

Week 7:

Tasks worked on:
-Started to work on USB mass-storage-class application bootloading
-Testing writing of images on different OSes

-elevation of privileges (root / admin) from nodejs code does not always work,
especially to run a binary for flashing

Goals for next week:
-continue to work on the image writing / flashing code
-integrate flashing tools download into the code and package within application
