Returns a "niceScaling" number approximately equal to the range.
Rounds the number if ROUND == true.
Takes the ceiling if ROUND = false.

@param RANGE the value range (maxValue - minValue)
@param ROUND whether to round the result or ceil
@return a "niceScaling" number to be used for the value range
