This file contains the ReadonlyMap algebraic data type. ReadonlyMap is a built in data structure in javascript that allows the association of arbitrary key anv value pairs. Generally, keys in a ReadonlyMap are only equal if their memory addresses are equal. This means that while strings and numbers work as expected as keys, complex objects such as [1] or { one: 1 } do not. Thus, there are many utility functions in this file that allow one to specify how to determine equality for keys in a ReadonlyMap.
