PackedVec

A PackedVec stores vectors of integers efficiently while providing an API similar to Vec. The basic idea is to store each element using the minimum number of bits needed to represent every element in the Vec. For example, if we have a Vec<u64> with elements [20, 30, 140], every element wastes most of its 64 bits: 7 bits is sufficient to represent the range of elements in the vector. Given this input vector, PackedVec stores each elements using exactly 7 bits, saving substantial memory. For vectors which often contain small ranges of numbers, and which are created rarely, but read from frequently, this can be a significant memory and performance win.
