/**
 * @name devshareConnect
 * @extends React.Component
 * @description Higher Order Component that automatically listens/unListens
 * to provided devshare paths using React's Lifecycle hooks.
 * @param {Array} watchArray - Array of objects or strings for paths to sync from Firebase
 * @return {Function} - that accepts a component to wrap and returns the wrapped component
 * @example <caption>Basic</caption>
 * // this.props.devshare set on App component as devshare object with helpers
 * import { devshareConnect } from 'react-redux-devshare'
 * export default devshareConnect()(App)
 * @example <caption>Data</caption>
 * import { connect } from 'react-redux'
 * import { devshareConnect, dataToJS } from 'redux-devshare'
 *
 * // sync /todos from devshare into redux
 * const fbWrapped = devshareConnect([
 *   'todos'
 * ])(App)
 *
 * // pass todos list from redux as this.props.todosList
 * export default connect(({ devshare }) => ({
 *   todosList: dataToJS(devshare, 'todos'),
 *   profile: pathToJS(devshare, 'profile'), // pass profile data as this.props.proifle
 *   auth: pathToJS(devshare, 'auth') // pass auth data as this.props.auth
