Example jar has invalid main class

[p013570]

This was introduced by issue gh-14 when packages were renamed.

We should probably just remove the main class and allow users to chose which example class to run on the command line.

Migration Steps

To run the examples on the command line you now need to specify which example to run by providing the class name as an argument and using 'java -cp' instead of 'java -jar'

java -cp example-jar-with-dependencies.jar gaffer.example.gettingstarted.analytic.LoadAndQuery1
