Another way to access the clickEncoder class

[aster94]

hello @soligen2010,

Reference: #8
In that issue i complained that that isn't the "arduino style" do use a class (even if an arduino style for writing libraries is not defined yet)
by the way with my surprise no edits was needed in the header and cpp file so this pull request contain only an example to use the library with the "arduino style" and a keywords.txt file to color the sintax inside the arduino ide

these methods are more user friendly for people who are approaching arduino for the first time

Thanks for your contribution. I am away from home so cant test it right now, so I'll test and merge when I get a chance. All looks good, so I expect it will test and merge just fine.

Perfect! I am happy to have been useful 😁 feel free to change the name of the example as you wish!
