"""

Sometimes you need to limit array result to use. Such as you only need the

value over 10 or, you need value under than 100. By use this algorithms, you

can limit your array to specific value

If array, Min, Max value was given, it returns array that contains values of

given array which was larger than Min, and lower than Max. You need to give

'unlimit' to use only Min or Max.

ex) limit([1,2,3,4,5], None, 3) = [1,2,3]
