Function wrapMutable

wrapMutable<T>(array: T[], cols: number): Geometry.GridArray1d<T>
Wraps array for grid access. Mutable, meaning that array gets modified if set function is used.
```
const g = wrapMutable(myArray, 5); // 5 columns wide
g.get({x:1,y:2});     // Get value at cell position
g.set(10, {x:1,y:2}); // Set value at cell position
g.array;              // Get reference to original passed-in array
```
Use wrap for an immutable version.
