adds translation support via i18n.js

Browse source 
Uses react-i18next library to provide APIs for translational
purposes.
Translation data is loaded from `src/locales/{{lng}}/translation.json`
and is accessed by dot notation.
The data can be translated in two ways:
1. In functional components, a method `t` can be instantiated using the
`useTranslation` method from rect-18next.
2. In class components, a method `t` can be accessed via props while
exporting the component with `withTranslation` method from react-i18next
library.

The syntax will look like `t('data.data')` or `this.props.t('data.data')`
