/************************************************************************
### Drone.arc() method
The arc() method can be used to create 1 or more 90 degree arcs in the
horizontal or vertical planes. This method is called by cylinder() and
cylinder0() and the sphere() and sphere0() methods.
#### Parameters
arc() takes a single parameter - an object with the following named properties...
* radius - The radius of the arc.
* blockType - The type of block to use - this is the block Id only (no meta). See [Data Values][dv].
* meta - The metadata value. See [Data Values][dv].
* orientation (default: 'horizontal' ) - the orientation of the arc - can be 'vertical' or 'horizontal'.
* stack (default: 1 ) - the height or length of the arc (depending on the orientation - if orientation is horizontal then this parameter refers to the height, if vertical then it refers to the length ).
* strokeWidth (default: 1 ) - the width of the stroke (how many blocks) - if drawing nested arcs it's usually a good idea to set strokeWidth to at least 2 so that there are no gaps between each arc. The arc method uses a [bresenham algorithm][bres] to plot points along the circumference.
* fill - If true (or present) then the arc will be filled in.
* quadrants (default: `{topleft:true,topright:true,bottomleft:true,bottomright:true}` - An object with 4 properties indicating which of the 4 quadrants of a circle to draw. If the quadrants property is absent then all 4 quadrants are drawn.
#### Examples
To draw a 1/4 circle (top right quadrant only) with a radius of 10 and
stroke width of 2 blocks ...
arc({blockType: blocks.iron,
meta: 0,
radius: 10,
strokeWidth: 2,
quadrants: { topright: true },
orientation: 'vertical',
stack: 1,
fill: false

### Copy & Paste using Drone
A drone can be used to copy and paste areas of the game world.
### Drone.copy() method
Copies an area so it can be pasted elsewhere. The name can be used for

#### Parameters
* name - the name to be given to the copied area (used by `paste`)
* width - the width of the area to copy
* height - the height of the area to copy
* length - the length of the area (extending away from the drone) to copy
#### Example
drone.copy('somethingCool',10,5,10 ).right(12 ).paste('somethingCool' );
### Drone.paste() method
Pastes a copied area to the current location.
#### Example
To copy a 10x5x10 area (using the drone's coordinates as the starting
point) into memory. the copied area can be referenced using the name
'somethingCool'. The drone moves 12 blocks right then pastes the copy.

### Drone.garden() method
places random flowers and long grass (similar to the effect of placing bonemeal on grass)
#### Parameters
* width - the width of the garden

#### Example
To create a garden 10 blocks wide by 5 blocks long...
garden(10,5);

/************************************************************************
### Drone Movement
Drones can move freely in minecraft's 3-D world. You control the
Drone's movement using any of the following methods..
* up()
* down()
* left()
* right()
* fwd()
* back()
* turn()
... Each of these methods takes a single optional parameter
`numBlocks` - the number of blocks to move in the given direction. If
no parameter is given, the default is 1.
To change direction use the `turn()` method which also takes a single
optional parameter (numTurns) - the number of 90 degree turns to
make. Turns are always clock-wise. If the drone is facing north, then
drone.turn() will make the turn face east. If the drone is facing east
then drone.turn(2) will make the drone turn twice so that it is facing
west.
### Drone Positional Info
* getLocation() - Returns a native Java Location object for the drone
### Drone Markers
Markers are useful when your Drone has to do a lot of work. You can
set a check-point and return to the check-point using the move()
method. If your drone is about to undertake a lot of work -
e.g. building a road, skyscraper or forest you should set a
check-point before doing so if you want your drone to return to its
current location.
A 'start' checkpoint is automatically created when the Drone is first created.
Markers are created and returned to using the followng two methods...
* chkpt - Saves the drone's current location so it can be returned to later.
* move - moves the drone to a saved location. Alternatively you can provide a Java Location object or x,y,z and direction parameters.
#### Parameters
* name - the name of the checkpoint to save or return to.
#### Example
drone.chkpt('town-square');
//
// the drone can now go off on a long excursion
//
for ( i = 0; i< 100; i++) {
drone.fwd(12).box(6);
}
//
// return to the point before the excursion
//
drone.move('town-square');
