A Vector is a collection of values indexed by contiguous integers. Vectors support access to items by index in log32N hops. Count is O(1). Conj puts the item at the end of the vector.

// Create an empty PersistentVector and add some elements
PersistentVector<string> vector =
PersistentVector<string>.Empty()
.Conj("hello")
.Conj("world")
.Conj("!");
Console.WriteLine(vector[0]); // hello
Console.WriteLine(vector[2]); // !
// Check no. of elements in the PersistentVector
Console.WriteLine(vector.Length); // 3

PersistentVectors are immutable and therefor allow to create new version without destruction of the old ones.
