Mention autoreconf in the installation instructions
Conditionally define AM_DEFAULT_VERBOSITY

Older versions of Automake don't define AM_DEFAULT_VERBOSITY.  This
leads to a problematic recursive definition of SILENT_MAKE_.  This
revision defines AM_DEFAULT_VERBOSITY to 1 but only if it's not
already defined.
Initial SWIG support for the bfbin library
Fixed two bad-pointer problems
Replaced condition variables and mutexes with barriers

pthread_cond_signal() doesn't guarantee that the signal is delivered.
Specifically, if no threads are waiting on the condition variable,
pthread_cond_signal() does nothing.  This revision replaces the
handshake protocol with one based on pthread_barrier_wait(), which
seems to work so far.
Began writing a Python demonstration of the SWIG interface
Rewrote the thread IPC to use Unix pipes

This is a much simpler approach than the previous attempt at using
barriers, and it actually seems to work so far.
Completed the example of invoking bfbin from Python
Install bfbin2py in the share/doc/byfl/examples/ directory
