Changed displaying numbers to a function
Changed function to usual integers instead of patterns and changed common
 number to usual integer instead of CM1, CM2, etc...
Changed hardware driver so arduino pins 0 and 1 can be used for the serial
driver. Added a 'Hellow World' to prove this works.
Now input 4 numbers to display and if over numbers are inputted, that number
 then becomes the first number of the next displayed set.
SLightly changed from last update
