Create structure for CoreImage kernels writeup
Create a playground to demo custom CoreImage kernels
Doesn't actually work because CIImage isn't liked in playgrounds
Create a single-view project instead of a Playground
License and boilerplate
Created VC with passthrough colour filter. Now to add chromakeying
Created the ChromaKey filter

And it works. Should update it to edit the threshold live. That'd be cool
Parameterise the filter on threshold
Allow live fiddling with the chromakey threshold

It's a bit slow in the simulator, but quite cool :)
WIP: Structure for the median filter

This doesn't currently work, but it creates the necessary structure for
the median filter.
Implement a motion blur filter
Removing the playground - it doesn't work
Implement the Sobel filter
Renamed the files and classes to match the new filter
Add some icons to the tabs
Remove an extra use of Median - should be Sobel
Intro to custom kernels and article outline
Completed custom kernels writeup
