Problem 1237. It's race time! Write a faster function than the test suite call of unique().

Created by Jeremy

Write a function to get unique elements of a vector faster than unique()! Input will be a vector (of integers or floating point numbers) of any size. The order of the returned vector is unimportant.

Example: Input: x = [1 1 2 2 3 3]; Output: [1 2 3];

Input: x = [0.1 3.1 2.1 2.0 3.1]; Output: [0.1 3.1 2.1 2.0]; % or any order
