Exercise: Calculating the array mode
Write a method mode which takes an Array of numbers as its input and returns an Array of the most frequent values.

If there's only one most-frequent value, it returns a single-element Array.

For example,

mode([1,2,3,3])         # => [3]
mode([4.5, 0, 0])       # => [0]
mode([1.5, -1, 1, 1.5]) # => [1.5]
