added tests + multiple bug fixes + UTF-8 robustness

Looks like this gem is unmaintained 😞

If you still need to use it, you might want to consider these updates and fixes:

• applied all the outstanding PRs of the original gem
• fixed gemspec file and Rakefile to be modern style
• removed unused ./test directory
• added RSpec tests
• converted RSpec tests to RSpec 3 syntax
• cleaned up Ruby style
• fixed and simplified regular expressions
• fixed parsing so it does not break names with UTF-8 characters!
• allowing 2nd, 3rd, 4th, Nth
• added lots of test cases
• fixed bugs in the parsing
• stripping spaces from titles and suffixes
• recognizing double middle names (might require you to do post-processing for double last names)

it's important to use \p{Word} instead of [A-Za-z] or \w+, so UTF-8 characters are included!
