Add exponential smoother to eg and update data structure

* Exponential smoother added to examples
* Organize properties of accelerometer
* Add getters and setters for data, remove 'last' object and just store
a queue
* bind smoother to accelerometer regardless of choice.
update pitch and roll with getters

also some ogranization for properties and getting everything inside
80chr.
update axis change determination

I'm not sure yet if I want to pass in the axes or get them from the
object keys.
set exponential smoother as default

* remove getter (didn't add anything but brittleness)
* default alpha value is quite aggressive
axisChange method accepts just data
Simplify enqueing function move data initialization out of constructor
remove binding for accelerometer and avoid side effects

* default smoother now accepts an arguments object as well
* and also does not rely on the binding of this for the inner or outer
function.
move smoother out of constructor.
adding temperature sensor example
Added Arduino Attack! to the awesome list.
