Support for smooth acceleration/deceleration in run (#900)

* removed logging

* removing more logging

* always use step for single/multiple motors

* refactored schedule

* account for accel ramp up and down

* added default acc/decel

* rounding speed/angle

* remove hack

* use acceleration time in run too

* handle missing case

* adding notes on motors

* adding sample

* fixed ramp simulation

* clear defaults

* some docs, more later

* adding basic examples

* remove debug msg

* clean json

* added move schedule

* docs

* basic docs

The speed setting is a pecentage of the motor's full speed. Full speed is the speed that the motor runs when the brick supplies maximum output voltage to the port.
The speed setting is a percentage of the motor's full speed. Full speed is the speed that the motor runs when the brick supplies maximum output voltage to the port.
If you use just the **speed** number, the motor runs continously and won't stop unless you tell it to. You can also give a value for a certain amount of distance you want the motor to rotate for. The **value** can be an amount of time, a turn angle in degrees, or a number of full rotations.

## Multiple motors
When using **run** with multiple motors, there is no guarantee that their speed will stay in sync. Use [tank](/reference/motors/tank) or [steer](/reference/motors/steer) for synchronized motor operations.
```blocks
motors.largeBC.run(50)
```
## Examples
### Drive the motor for 20 seconds

# Schedule
Schedules an acceleration, constant and deceleration phase at a given speed.
```sig
motors.largeA.schedule(50, 100, 500, 100)
```
The speed setting is a percentage of the motor's full speed. Full speed is the speed that the motor runs when the brick supplies maximum output voltage to the port.
## Parameters
* **speed**: a [number](/types/number) that is the percentage of full speed. A negative value runs the motor in the reverse direction.
* **acceleration**: the [number](/types/number) of movement units to rotate for while accelerating.
* **value**: the [number](/types/number) of movement units to rotate for.
* **deceleration**: the [number](/types/number) of movement units to rotate for while decelerating.
* **unit**: the movement unit of rotation. This can be `milliseconds`, `seconds`, `degrees`, or `rotations`. If the number for **value** is `0`, this parameter isn't used.
