Irmin.CommitCommit values represent the store history.
Every commit contains a list of predecessor commits, and the collection of commits form an acyclic directed graph.
Every commit also can contain an optional key, pointing to a node value. See the Node signature for more details on node values.
module type S = sig ... endmodule type Maker = sig ... endMaker provides a simple implementation of commit values, parameterized by commit info.
module Generic_key : sig ... endGeneric_key generalises the concept of "commit" to one that supports object keys that are not strictly equal to hashes.
module V1 : sig ... endV1 serialisation.
module Portable : sig ... endPortable form of a commit implementation that can be constructed from a concrete representation and used in computing hashes. Conceptually, a Commit.Portable.t is a Commit.t in which all internal keys have been replaced with the hashes of the values they point to.
module type Store = sig ... endStore specifies the signature for commit stores.

module type History = sig ... endHistory specifies the signature for commit history. The history is represented as a partial-order of commits and basic functions to search through that history are provided.
