ref issue #15 - Added default empty string values for title and titleSuffix to avoid 'undefined' string - Added setDefaultTag for resetting defaults after the config stage   - known issue: line 130: if resetting default titleSuffix from empty string, while title is not default, suffix is not appended (to avoid situation where non-default suffix is already set by state, and therefore having a double suffix)
