[New Language] Solution in GNU Octave

Solution in GNU Octave probably works in MATLAB too but I have only tested in octave. 

To run the script:

```
#If necessary install octave
sudo apt-get install octave #or your package manger of preference
cd goal/solutions/complete/octave/ShaneQful
octave # launches octave console
#In the octave console
octave:1> source goal.m
```
