OK! Except for some tiding up, the desired functions are working. Uh, sort of. Now it's time to make the Sweeper class easier to use and to add some helper functions to do interesting things - like group moves perhaps. For those playing along at home, this will be the useful version!

Step 1: Fix the Sweeper class so that no arguments are required to instantiate a Sweeper object. Why? Because an array of Sweepers can now be created. This keeps the code for creating, initializing, and updating the servos nice and clean.

Step 2: Add some useful class functions. The code to initialize a move with destination and time is now separate from the function that enables the move. Doing this allows several moves to be set up, then all started at the same time, for a group move. Now it is likely that this is not necessary in most cases, but I thought it would be nice to have and would eliminate worries caused by starting moves at staggered times.

Step 3: Create a "group move" function. The idea here is to allow a group of servos to be easily defined (as an array), along with a corresponding array of target angles and an allowed time for the move.

Step 4: Time the worst case operation. Suppose all the Sweepers need to move on the same tick. Will there be time or will there be a timing conflict?

Still coming: video of a simple demo. Bonus: Lego link: Gear and Mount.
