DAQling DataTypes
Added an abstract DAQling DataType, to be passed around in connections. Template parameterized queues, to allow these to hold different datatypes, based on what the module owning the queue wishes to pass. Added the SubTypes DataFragment, and SharedDataType, to be used as generic classes for managing the lifetime of an inner object. The DataType and subclasses provide support for zmq zero-copy.
