# Serializable provides functionality around serialization to the classes that
# extend it. This includes a class method to deserialize a string and create an
# instance of the class.
module Serializable
# @param str [String] the serialized object string
# @return [Object] the object represented by the serialized string
# Note: this method assumes the calling class provides the following methods:
# - deserialization_regex
# a regex for the string which includes named parameters for the
# different initializer arguments
# - deserialization_expectation
# a string for what was expected, if the regex does not match
