Class Dotter() simply types symbols (dots in default) on screen. This may be used to make clinets aware that some computing is still happening in background. Symbol and delay in miliseconds can be defined at class initalization or set at any time.

##Examples:

from dotting import Dotter
from time import sleep
d=Dotter()
d.start()
sleep(3)
d.stop()

from dotting import Dotter
from time import sleep
d=Dotter(200,',')
d.start()
sleep(2)
d.set(symbol='.')
sleep(3)
d.stop()
