// An extremely basic translation library
//
// Example usage:
//
// Set some html to be translated. Do this using the 'data-translate' attribute:
//
//   <div data-translate>Test</div>
//   <div data-translate-html><em>keep em tag</em></div>
//   <input data-translate-placeholder placeholder="Example placeholder">
//   <span data-translate-title title="Example title"></span>
//
// Obtain all the phrases to be translated via js debug console:
//
//   Translate.phrasesAsJson();
//
// Use that template to translate the phrases into another language.
// Leave the key the same. Change the value to the new language.
//
// Create a js file to load the new phrases. In this example for Spanish,
// es.js will contain the following code:
//
//   Translate.loadForeignPhrases("es", {
//       "Test": "Test in Spanish",
//       "<em>keep em tag</em>": "<em>keep em tag in Spanish</em>",
//       "Example placeholder": "Example placeholder in Spanish"
//       "Example title": "Example title in Spanish"
//   });
//
// In your UI put a listener for clicking on the Spanish button:
//
//   mySpanishButton.addEventListener("click", function() {
//       Translate.setLanguage("es");
//   });
//   myEnglishButton.addEventListener("click", function() {
//       Translate.setLanguage("en");
//   });
