Overview

This class includes a workaround patch, providing a solution of the unaccepted pull request ‘false is not overriden by true if preserve_unmergeables’ github.com/danielsdeleo/deep_merge/pull/28

It ensures, that booleans can be merged correctly, by en- and decoding them to strings, before and after merging see #encode_boolens and #decode_booleans
