Now we have the folder "GMGridView" with the grid classes + an xcodeproj to build.
Next, there is "Example" which uses the new GMGridView.xcodeproj to link against the project.
This matches style with most other popular open source projects, and makes it easier to see what's the actual source code and what's the example. This was too mixed up previously.
This change allows to set if an insert/update/etc should be animated or not.
It also allows adding a "scroll to action" with an extra animation flag.
Also, per default, property changes *don't* animate. We need more control here,
and setting a property never should automate *per default*. We can manually start
a animation after setting a property with layoutSubviewsWithAnimation, as seen in the updated example project.
The dataSource now has a canDeleteItemAtIndex asking each cell before setting it to editable.
The deleteItemAtIndex has been renamed to shouldDeleteItemAtIndex and is now a member of the ActionDelegate.
If not implemented, YES is assumed, if it's there and NO is returned, the item won't be deleted automatically.
