*** empty log message ***
Initial check-in of Kallia's code. Not working on exqstruct example.
Working on hyperqueue implementation
Moved queue_version into tags/queue_t - no more dynamic memory allocation
More development. Struggling with queue reduction.
Significant progress
Further progress

Remaining issues:
* improve popdep scheduling (tickets.h): avoid launch pop3 in:
push0 pop0 pop1 push1 pop2 pop3
before pop1 has finished.

* there are locking bugs in queue_version.h
Tickets behavior restored. No sync required - push "renames", pop "polls"

* May consider to include into pop ready/ini_ready whether queue has
  been published in parent
This seems to be working but is still inefficient wrt locking
Removed debug printing
remove redundant code
Streamlining operations on half-lists / segmented_queue's
Completed hypermap definition to mere hypermaps at sync
Updates to setting producing flag and checking emptiness
Bug fix
Import bzip2 benchmark and several variations.

This code is based on the Cilk++ distribution.
Queue-based version of bzip2
Bug fix.
Included missing include files for Linux and updated Makefile for hwloc
Make default main() and my_main() weak symbols
