Function addBundle

addBundle(bundle): void
JMap.Language.addBundle

This method lets you add your own translations into JMap Server NG translation engine (for instance, all translations needed for one of your extensions)

Once added, a bundle cannot be overriden, and its identity must be unique (its id). You can specify a default locale for your bundle, in wich case the JMap Server NG translation engine will fall back to your bundle's default locale instead of on the system's default locale if a translation is not found in your bundle for the current locale.
Parameters
- bundle: JTranslationBundle
  a JTranslationBundle object
Returns void
Throws
if bundle is invalid or already defined

Example
```
// Supported locales can be retrieved by calling JMap.Language.getLocales()

const bundle = {
 id: "my-custom-bundle-id",
 defaultLocale: "fr",
 translationsByLocale: {
   "fr" : {
     "my-custom-key": "Ceci est ma traduction personnalisée en français"
   },
   "en" : {
     "my-custom-key": "This is my custom translation in English"
   }
 }
}
JMap.Language.addBundle(bundle)
JMap.Language.setLocale("fr")
let params = {key: "my-custom-key", bundleId: "my-custom-bundle-id"}
console.log(JMap.Language.translate(params))
// "Ceci est ma traduction personnalisée en français"
```
