/// \class command_queue
/// \brief A command queue.
///
/// Command queues provide the interface for interacting with compute
/// devices. The command_queue class provides methods to copy data to
/// and from a compute device as well as execute compute kernels.
///
/// Command queues are created for a compute device within a compute
/// context.
///
/// For example, to create a context and command queue for the default device
/// on the system (this is the normal set up code used by almost all OpenCL
/// programs):
/// \code
/// #include <boost/compute/core.hpp>
///
/// // get the default compute device
/// boost::compute::device device = boost::compute::system::default_device();
///
/// // set up a compute context and command queue
/// boost::compute::context context(device);
/// boost::compute::command_queue queue(context, device);
/// \endcode
///
/// The default command queue for the system can be obtained with the
/// system::default_queue() method.
///
