Examples

[sshanks-kx]

May be useful to have some examples, if this can be compiled as part of the travis job, but avoiding being packaged up with the main lib.
Rather than code being on a doc, it'd make sure the code still builds with any potential changes made to the interface.
Some examples were on https://github.com/KxSystems/javakdb - these also included a bit of a guide to how to run (for someone thats never used kdb before, but might want to see something running). Note: the java docs for examples prob need improved further.
