title: How to make Angular ng-grid cell editable via binding?
body: <p>Just starting out with ng-grid.  I need to make individual cells (i.e. for a given row and column) editable based on the boolean value of a property in my grid array.  It would be great if I could simply bind to the array property to turn on (or off) cell editing.  However, I don't see this option available.  Did I overlook something, does ng-grid support this out of the box?  If not, any suggestions as to how I could implement this feature?</p>
