Add a Note that Dict.get is O(n)

[alexanderkiel]

You have a nice implementation of a Dict here. But others should know from the start that Dict.get is O(n) so that they can decide whether they can use it.

Hey there!

Yes, I think you're right, that should be in the readme. One caveat is that the Dict is not O(n) in the number of elements, but on the number of insertions.

[alexanderkiel]

Hi! Yes the n is the number of insertions.
