19ec7c78a1 ConcaveBoundaryTest unit test 
This is from the case I originally got to trigger the problem.  We could
probably boil it down to something smaller (by temporarily reverting the
Orient2d change to make sure the failure still occurs) but this doesn't
seem too bloated for a unit test as-is.

57b3039c05 Disable tolerance in Orient2d collinearity test 
This fixes failures for me when trying to triangulate
concave-by-less-than-epsilon boundary polylines.

4581f1fee8 Consistent executable path in README.md 
These commands run (from the source directory; would commands as run
from the build directory be clearer?) for me as-is (after the testbed
executable has been built) now.

4fd0287f04 Fix, clarify build instructions 
If we're in a build subdirectory, we need `..` to tell cmake where to
find the source directory.

ebf0c4d987 Rename testbed/testbed to testbed/p2t 
That's what README.md has been referencing as the executable name, and
it's more meaningful.

8388a74a9f Improve testbed data file format 
Data file format now has optional sections for holes polylines
and Steiner points identified with tokens "HOLE" and "STEINER".

Rework the data file dude.dat accordingly.

Add data file steiner.dat for an example with Steiner points.

35b2fa916a Patch inversion of head and tail in the advancing front initialization

head_ to af_head_ and tail_ to af_tail_ as one would expect.

- Building unit tests is optional, disabled by default to prevent
  the library clients from pulling the dependency on boost
- Add the unit tests to the Github Actions.
- Use boost::filesystem to manipulate paths for better portability

e66d045060 Fix #11 - regression causing crash when abs(p1.y - p2.y) < 1e10 (#12) 
This reverts commit e0ba327ed8.

While the orignal commit silences a compiler warning, it introduces incorrect
behavior in Edge constructor that causes crash later during triangulation.

See #11 for an example of a simple polygon that would cause crash
