/**
 * @fileoverview Mock Radio Interface Layer (RIL) used for testing
 *
 * The following routines are defined in c++:
 *
 * Print a string to android log
 *   print(string)
 *
 * Read a file to a string.
 *   String readFileToString(String fileName)
 *
 * Read a file to a Buffer.
 *   Buffer readFileToBuffer(String fileName)
 *
 * Send an response unsolicited response to the framework.
 *   sendRilUnsolicitedResponse(Number responseNum, Buffer responseProtobuf)
 *
 * Send a completion request to the framework.
 *   sendRilRequestComplete(Number rilErrCode, Number reqNum,
 *                              String token, Buffer responseProtobuf)
 *
 * Send a complete request to the controller.
 *   sendCtrlRequestComplete(Number ctrlStatus, Number reqNum,
 *                              String token, Buffer responseProtobuf)
 *
 * Include the javascript file.
 *   include(string)
 *
 * The following objects are defined in c++
 *
 * Buffer is defined in node_buffer and provides a wrapper
 * for a buffer that can be shared between c++ and js.
 *   Buffer(length)
 *     Buffer::length()
 *     Buffer::data()
 *
 * Schema is defined in protobuf_v8 and converts between
 * a buffer and an object. A protobuf descriptor, ril.desc
 * and ctrl.desc, is used to drive the conversation.
 *     Object Schema::parse(Buffer protobuf)
 *     Buffer Schema::serialize(object)
 *
 * Worker is a thread which receives messages to be handled.
 * It is passed a function which is called once for each
 * message as it arrives. Call the add method to queue up
 * requests for the worker function to process.
 *   Object Worker(function (req))
 *      Worker::add(req);
