code: function classify(string) {
      string = string.replace(/[\W_](\w)/g, match => ` ${match[1].toUpperCase()}`).replace(/\s/g, '');
      return string.charAt(0).toUpperCase() + string.slice(1);
  }
docs: Convenient function to convert string into valid java class name
  Note: _.classify uses _.titleize which lowercase the string,
  so if the user chooses a proper ClassName it will not rename properly
  
  @param string string to 'class'-ify
  @returns {string} 'class'-ified string
