Fast movement on attach

[mike-lloyd03]

When I run servo.attach(SERVO_PIN, aMicrosecondsForServo0Degree, aMicrosecondsForServo180Degree), there is a rapid movement of the servo. It appears this is moving to the middle position (1500µs) but it moves as full servo speed. This will likely break things when it is installed in the application. Is there a way to set it to move to this initial position much slower? Or better yet, not to move to a position at all?

Servos are buld to reach the target position as fast as possible.
To achieve slow movement, this library gradually adjusts the target position,
and the servo attempts to respond to these changes as quickly as possible.
This creates the appearance of slow movement even when the servo reacts very quickly.

Initially, after powering on, the software has no information about the actual servo position!

This leads to the servo moving quickly to the start position that the software sends it. This cannot be avoided unless we can magically guess the actual position!
