Version 0.5.6 Released!

This release is mostly about making the system a bit more standards-compliant, adding some (literal) simplicity, and allowing for some automated testing. There were a few minor enhancements, the major one of which was the ability to return a "simple" array, which is devoid of the "value" and "attributes" sub-arrays for every tag, along with minor sanity fixes with exception handling. The release notes / change log is reproduced below:::
