/**
 * createTablePlugin creates a Plugin class which handles fetching data from the client and
 * displaying in in a table. The table handles selection of items and rendering a sidebar where
 * more detailed information can be presented about the selected row.
 *
 * The plugin expects the be able to subscribe to the `method` argument and recieve either an array
 * of data objects or a single data object. Each data object represents a row in the table which is
 * build by calling the `buildRow` function argument.
 *
 * An optional resetMethod argument can be provided which will replace the current rows with the
 * data provided. This is useful when connecting to Flipper for this first time, or reconnecting to
 * the client in an unknown state.
