Connection handle class for use in the HCI API.

Although THCIConnHandle is a valid type to use for representing a connection handle, as there are commands that require an array of the type to be provided, RArray instances are used as the API. The type contents RArrays use must be at a minimum 4 bytes in size. This class provides a 4 byte encapsulation of a 2 byte connection handle.
