modification of the demo app

[ghost-from-the-past]

Dear Mr. martin-stone
I found your library mentioned in https://ourcodeworld.com/articles/read/932/top-10-best-android-color-picker-libraries.
I was playing with it and I did a modification of the demo app to be capable of being call from another application via Intent+startActivityForResult
so the demo is and application in its own capable of receiving "request" and give back the color number.
The modifications are not so big, adding a Done button, add the intent-filter to the manifest and the Intent response in the MainActivity.
I guess is good idea to put this "demo" (now an app in its own) in the Play Store (and it continues to be a valid demo for your library). If you also thinks it is a good idea send me an email and I'll forward you the zip file with your modified project
