ServoEaser library for Arduino

2011, TeamPneumo, Tod E. Kurt, http://todbot.com/blog/

ServoEaser is an Arduino library makes doing animation-style movements with servos easier.

Features:

• Supports directly telling a servo to ease to a position over a duration
• Supports playing of previously-defined "move lists"
• User-specified easing functions (defaults to easeInOutCubic), see Easing lib
• User-specified "servo arrived" function for async callback when movement done
• Supports both integer angle movement and a "microseconds" mode for fine-grained control with float-ing point angles
• Works with both new Arduino 1.0 and Arduino 0022.
