Version Vector Dominates Check

Problem

Check whether one version vector dominates another.

a and b are version vectors as lists of integers. a dominates b when every element of a is at least the corresponding element of b, meaning b's history is fully contained in a's. Vectors of different lengths never dominate each other.

Return True or False.

Hint

Dominance is component-wise greater than or equal.
