Vault is a tiny library that provides a single data structure called vault.
A vault is a type-safe, persistent storage for values of arbitrary types. Like
Ref, it should be capable of storing values of any type in it, but unlike
Ref, behave like a persistent, first-class data structure.
It is analogous to a bank vault, where you can access different bank boxes with different keys; hence the name.

To use vault in an existing SBT project with Scala 2.12 or a later version, add the following dependencies to your
build.sbt depending on your needs:
libraryDependencies ++= Seq( "io.chrisdavenport" %% "vault" % "<version>" )
