code formatting, fixes PHPCS errors
Improvements to Hash::expand and Hash::merge.

Because of the recursion in these functions, processing very large
arrays would take a very long time. I rewrote the functions to
eliminate any unnecessary recursion and function calls. Large arrays
are now processed much faster.
Fixed coding standard violations.

This reverts commit 8507ef83f175bbf3f6532dc68b6051f0d41acd82.
