There are many ways to skin a cat. Some are simpler than others.
After some familiarisation with Simplicity Studio I have found and even easier way to open, build and test the examples.
Here's a silent video of the process.
All you need to do is;
Click the Examples tile in Simplicity Studio under the caption Software and Kits.
Select your Development Kit (in my case STK3700).
Select the example project you wish to open and build.
From here your selected IDE will open and you can download and debug.
Enjoy (This is best viewed in full screen mode).
For those who have not installed Simplicity Studio here is a short summary of the examples provided for the STK3700.

To date, I've tried the following examples with complete success;
blink This is the just another "Hello World" for microcontrollers and can be used as a template for new Giant Gecko projects.
clock This displays the time on the LCD.
inttemp This is preloaded thermometer application on the Giant Gecko.
touch This is a great demonstration of the Giant Gecko's capacitive sensing slider bar.
lcsense This is a great demonstration of the Giant Gecko's metal detection.
lightsense This is a great demonstration of the Giant Gecko's light sensing.
