v0.8

• An integration test that uses the main demo script (boosts the test coverage a lot)
• Improvements to how neighboring tiles are handling in type recipes.
• Non-convex tilings: Stanley Park, Islamic Hex and Stars, Islamic Stars and Crosses.
• More tiling types: Valemount, Cloverdale,
• More metadata: aspect ratio, which allows for rendering of nice looking 2D tilings (simple_2d option)
• "extra parameters" for Tessagon types (included in metadata). WeaveTessagon and BigHexTriTessagon have extra parameters.
• Mysterious parallelogram_vectors feature. It now drives the working of the rot_factor feature and allows for many possibilities (provided that you can figure it out)
• AlternatingTiles for specific types, and nascent rotational symmetry feature.
• Many refactorings of internal code
