/*
This shows the capabilities of the library text engine that is
extremely flexible and simple! All commands are the same for all type of text
(INT,EXT or Render ones) and things like println works too.
You can use all the print() options (like print(var,HEX), etc. Take a look the print command 
in the arduino guide!)
