class AWS::Core::IndifferentHash

A utility class to provide indifferent access to hash data.

Inspired by ActiveSupport’s HashWithIndifferentAccess, this class has a few notable differences:

ALL keys are converted to strings (via to_s)
It does not deep merge/convert hashes indifferently, good for fla
It will not perserve default value behaviours

These features were omitted because our primary use for this class is to wrap a 1-level hash as a return value, but we want the user to access the values with string or symbol keys.
