Add IntTicks
Created by: isa9660
Nice to meet you. Thank you for a wonderful library. In order to easily represent integers, I created 'IntTicks'. By the way, if you change 'DefaultTicks' in 'Custom tick marks' of example to 'IntTicks', it will have the same result as the example. ('1,.5e,+04'->'15,000','1e,+04'->'10,000)
