Some edge cases

[thommeo]

Hi thank you for the great library.

I have discovered some names, that the conversion produces unexpected results.

Here are my test cases:

[
"Yuri's",
"van den Thillart",
"Ruiz y Picasso,"
"Dato e Iradier",
"Mas i Gavarró",
"Fred XLIX",
"Yusof bin Ishak"
]

The names are taken from Ruby variant of the library: https://github.com/tenderlove/namecase/blob/master/test/test_namecase.rb

Here are the results:

  1) Capitalize name
       should convert "YURI'S" to "Yuri's":

      AssertionError: expected 'Yuri\'S' to equal 'Yuri\'s'
      + expected - actual

      -Yuri'S
      +Yuri's

  3) Capitalize name
       should convert "RUIZ Y PICASSO" to "Ruiz y Picasso":
