## Interpolation
### Instructions
Create a function called `interpolation` that takes an object with 5 properties
`step`, `start`, `end`, `callback` and `duration`.
This function must calculate the interpolation points, (x, y),
from the `start` position to `end` position depending on the number of `steps`.
All the points must be calculated in the duration time.
For each interpolation point you must execute and pass as parameters to the callback the interpolation point ([x, y])
### Example
```
steps = 5
start = 0
end = 1
duration = 10
t
|
10 |___________________. <- execute callback([1.0, 10])

| |
8 |_______________. |

6 |___________. | |
