Public Class methods

_blank?(obj)

Can‘t use regular empty? because that affects strings.

subtract_arrays(arr1, arr2)

Non-destructive version of above method.

subtract_arrays!(arr1, arr2)

Regular array difference does not handle duplicate values in the way that is needed for this library. Examples: 

  subtract_arrays([1, 1, 2, 3], [1, 2]) => [1, 3]
  subtract_arrays([3, 3, 3, 4], [3, 4, 5]) => [3, 3]
