• pendulum — swinging pendulum wave (120 frames, 10 chars)
• compress — data compression visualization (100 frames, 10 chars)
• sort — sorting visualization with sweep cursor (100 frames, 10 chars)

New public API

• brailleBase — Braille character base codepoint (U+2800)
• dotBits — dot bit map for direct Braille bit manipulation

1.0.1

• Added example/example.dart so the package example is detected by pub.dev (Improve pub.dev score)
