Add links to examples on Github

[svenvNL]

The documentation has a lot of example code. Most examples are not complete, some of it are (incomplete) spec files, other examples are JavaScript or Python code. I find it helpful to have fully working examples so I don't have to piece bits of documentation example code together for a working example.

Having all source code for an function in the docs is less then ideal (hence why all examples are incomplete). I would propose to have a link to the file on Github when there is a code example so the complete file and accompanying files for a function can be looked at.

Here are examples by Google.
