* Method: read
* APIMethod: read
* Parse the response from a transaction. Because WFS is split into
* Transaction requests (create, update, and delete) and GetFeature
* requests (read), this method handles parsing of both types of
* responses.
*
* Parameters:
* data - {String | Document} The WFST document to read
* options - {Object} Options for the reader
*
* Valid options properties:
* output - {String} either "features" or "object". The default is
* "features", which means that the method will return an array of
* features. If set to "object", an object with a "features" property
* and other properties read by the parser will be returned.
*
* Returns:
* {Array | Object} Output depending on the output option.
