Vector builder

An API for efficient and convenient construction of vectors. It provides the composable `Builder` abstraction, which has instances of the `Monoid` and `Semigroup` classes. [Usage] First you use the `Builder` abstraction to specify the structure of the vector. Then you execute the builder to actually produce the vector. [Example] The following code shows how you can efficiently concatenate different datastructures into a single immutable vector:>>import qualified Data.Vector as A>import qualified VectorBuilder.Builder as B>import qualified VectorBuilder.Vector as C>>>myVector :: A.Vector a ->[a] ->a ->A.Vector a>myVector vector list element =>C.build builder>where>builder =>B.vector vector<>>B.foldable list<>>B.singleton element.
