This Speed Performance Challenge is to optimize Unique for processing uint8/uint16/uint32 variables.

Input: A (column vector of uint8/uint16/uint32)

Output: B (column vector A processed by unique "like" function)

Scoring: Cumulative time, in msec, of "unique" processing of three medium size arrays.

Examples: [5;4;3;2;2;1] returns [1;2;3;4;5], and Fast
