Installing the developer mode app on Gear S2

There are two methods of installing a developer mode app on Gear S2. For part 1, we will cover installing via widget file (.wgt). It is a quick way to install from the command line. If you have the source code for the developer app then you could install from Tizen IDE. However, we will cover that in the part 2.

Installation method #1: Command Line (if you have .wgt file)

Update the path so you can run sdb.exe from any location
