Project restructuring ...

• directory structure updated to make the repository hopefully a little more scalable for other components (and other future contributors).

• merged a refactoring of the mrpd code from audioscience. Many thanks and Andy and team for cleaning up the string syntax as well as breaking up the monolithic mrpd.c. As a result right now however, the simple_talker example application needs to be updated with the updated mrpd configuration syntax.

• posted the Intel gptp daemon source code - both Windows and Linux versions. The Windows version however requires as of yet not-publically available NDIS drivers to interop with.

• Simple_talker was updated to include simple audio format 61883 streaming of a mono audio tone. It also requires the aforementioned gptp daemon to provide the 802.1AS time.

• Updated the project readme to state the project goals, contribution guidelines, etc. as well as a few callouts to the other open-source repositories from JeffK and XMOS.
