Trainstation animation style [JDClassicFlipNumberView]

[calimarkus]

When changing a number, e.g. 3520 to 9250 every digit should animate on its own to the new number iterating over every digit inbetween.

Means:
3 to 9 (in 6 flips)
5 upwards to 2 (in 7 flips)
2 to 5 (in 3 flips)
0 stays like it is (0 flips)

IIRC, in real displays, the numbers flip independently, but only one way, never backwards.

yes that is how i meant it :) you may start with your PR :D

Ah, right, I just read "upwards" on your 2nd example and ignored the number ;-)
