handleSuggestions function of latin.js in keyboard is modified to handle capitalization of letters in suggestion mode

latin.js

function handleSuggestions(input, suggestions) {
  function isCapitalized(word) {
    return word.toLowerCase() !== word;
  }

  function capitalize(inputword, suggestionWord) {
    var result = suggestionWord;
    for (var j = 0; j < inputword.length; j++) {
      if (isCapitalized(inputword[j])) {
	result = result.substring(0, j) + result[j].toUpperCase()
	           + result.substring(j+1);
      }
    }
    return result;
  }

  function wordBeforeCursor() {
    return inputText.substring(wordStartBeforeCursor(), cursor);
  }

  var typedWord = wordBeforeCursor();
  if (input !== typedWord || typedWord.length == 0) {
    //user typing faster than suggestions provided or 
    //the length of typed word is zero
    keyboard.sendCandidates([]);
  } else {
    if (typedWord.toLowerCase() !== typedWord) {
      //capitalize all of the suggestions comparing to input string
      for (var i = 0; i < suggestions.length; i++) {
        suggestions[i] = capitalize(typedWord, suggestions[i]);
      }
    }

    keyboard.sendCandidates(suggestions);
  }
}
