# YOUR MISSION

An [octahedron](https://en.wikipedia.org/wiki/Octahedron) is an 8-sided polyhedron whose faces are triangles. 

Create a method that outputs a 3-dimensional array of an octahedron in which the height, width, and depth are equal to the provided integer `size`, which is equal to the length from one vertex to the opposite vertex on the octahedron.

## EXAMPLE

```python
create_octahedron(7)

where each 1 represents a cubic unit that the octahedron takes up and where 0 is a cubic unit of empty space.

# NOTES

 - The method should return an empty array/list if either 
  - The input size is even (because then it wouldn't be an octahedron. It'd be an irregular polyhedron with 26 sides)
  - if the input size is 0 or less
  - if input size is 1 (that's called a cube).
 - If there's any problems with this kata (*COUGH* [my last Kata](https://www.codewars.com/kata/5bf76f953efcee37e2000061) *COUGH*), I'll try to get them fixed in the evenings before 10pm.
