Now works without Redux by defualt.
Add LoclaizeProvider a wrapper around React's Context.Provider
Add LocalizeContext built on React.createContext.
Add withLocalize higher-order component
Add onMissingTranslation initialize option that provides more control over handling missing translations.
Optionally supports Redux by passing redux store to LocalizeProvider.

Breaking Changes

The Redux action creators initialize, addTranslation, addTranslationForLanguage, and setActiveLanguage have been removed. Instead they are now methods available on LocalizeContext, and can be added to your component's as props using the withLocalize higher-order component.
The translationTransform option is no longer available as an initialize option. Instead addTranslation now takes an options object, which accepts the translationTransform function.
- This made more sense as this allows for adding transformations specific to a single translation instead of globally setting a transformation that you'd be stuck using for all translations.
initialize now takes a single options argument instead of multiple arguments.
Translate render props API now takes a single options object as an argument instead of multiple arguments.
renderInnerHtml option now set to false by default instead of true.
- This is to mirror React's functionality where by default any children will be escaped by defualt.
Remove showMissingTranslationMsg, missingTranslationMsg, missingTranslationCallback initialize options. THe new onMissingTranslation option now covers all these scenarios.
Remove setTranslations action - instead pass languages to initialize.
Remove localize higher-order component - use new withLoclize higher-order component instead. Or if you only require access to translate function use <Translate> component instead.
If using Redux, all state related to localize will be added under the localize key instead of locale.
If using Redux, localeReducer is now named localizeReducer.
