Most functions in LinkedList have time complexities in their description:
Like push front:

Adds an element first in the list.

This operation should compute in O(1) time.

Time complexities were missing for the following, so I've added them in this PR:

contains: O(n)
front: O(1)
front_mut: O(1)
back: O(1)
back_mut: O(1)

Consistent big O notation

This makes the big O time complexity notation in places with markdown support more consistent.
