Libspiro, version 0.5.20150702

Spiro is the creation of Raph Levien, which simplifies the drawing of beautiful curves.
Libspiro is a shareable library that can be used by programs to do the Spiro computations for you.

Main improvements you may notice in this release are:

1. Re-edit of libspiro to compile across more and older compilers.
2. Bug fix in call-test.c to sawtooth through POSIX test for platforms
   that have less (or more) than 300 (minimum) threads available at a time.
3. Verified data check (versus visual inspection) to ensure libspiro works.
4. Separated call-test into 6 different tests for easier determination of
   if libspiro is passing or failing (call-testm still does over 3000 tests).
5. Display configure flags (normally hidden by run silent/quiet mode, plus
   added LS_CFLAGS and LS_LIB overrides if you want to use other flags instead
   of the auto-inserted defaults.
