SimpleServo - v0.8
==================

"Shh, ya hear that?  Me neither… It's simple… Maybe *too* simple…"

This is a simplistic library to bundle up and generalize bit-banging servo PWM.  It has some good points and trade-offs and is primarily being developed for the Digispark.

First the good: 
  - Can control any number of servos
  - All software, no fancy hardware required
  - Produces a relatively clean signal
  - Allows (or will) tuning pulse parameters to suit the widely varied tastes of different servos
  - A single instance can be used with multiple similar servos

Now some limitations:
  - It can only control one servo at a time
  - The program can't do anything else while the servo is being signaled 
  - Documentation is incomplete (at the moment)

When typical servos stop receiving a control signal, they stay where they are; while they won't actively hold their position, most require some force to backdrive.  So if that's enough for your project, you can move each servo in turn, and sample inputs, set LEDs and such in between.

See comments in SimpleServo.h (and SimpleServo.m) for now.

*(( TODO: Document the additional methods in detail, add an example ))*
