Minor documentation fixes

Updated README.md and ServoSequence.ino example.

Simplified sequencePlay

This release simplifies how sequences are used, eliminating the need to initialize a sequence.

Added a new stop() function to stop a servo immediately where it is.

Bug fix for write(int, int, boolean) to allow microseconds

Fixed write(int, int, boolean) to work with microseconds for the first parameter that sets the position. The function will now detect if the value passed for the position is valid for microseconds / pulse width - i.e. >= 544.

Position sequencing added

This release adds the ability to create and use different positional sequences that run asynchronously.

Initial release with documentation fix

An initial release of an updated version of VarSpeedServo.h by Korman, who adapted it from the standard Arduino servo.h library.
