Readme needs clarification

[RSully]

The read me could be expanded a bit in some of the following ways:

• [ ] Make delegation more obvious
• [ ] Clarify that the main view is only the color picker, and that that you're not forced to use the badly laid out example controller (I'm afraid people might look at the screenshots and be turned away)
  • [ ] Update example project for better layout/etc :wink: (also see #34)
  • [x] Make custom sliders less obvious - not really meant to be used

I'm thinking it might help if there were links or screenshots of apps using this component. If anyone has info about this drop it here!

Anyone can add their apps to this list now: https://github.com/RSully/RSColorPicker/wiki/Apps-using-RSColorPicker
