Contains base error classes for errors defined in the Batterii organization.
Makes use of Nani to enable easy and robust run-time checking against error type heirarchies, which is usually not possible in JavaScript or, by extension, TypeScript.
This exists primarily for namespacing purposes and will likely only ever
contain a single class, BatteriiError, which should be the base class for
every error defined in any package with the Batterii scope, or any open-source
package we might end up having that is maintained by Batterii but is not
released under the scope.
If we publish (either publicly or privately) a package called
@batterii/encode-object, for example, any errors it defines should derive from
an EncodeObjectError, which in turn derives from BatteriiError.
