docstring: Case Determination according to the needs of BibTex
  
  To parse the Author(s) correctly a determination is needed
  to get the Case of a word. There are three possible values:
  - Upper Case (return value 1)
  - Lower Case (return value 0)
  - Caseless   (return value -1)
  
  @access private
  @param string $word
  @return int The Case
  @throws BibtexException
