Description

Changed description of ItemSelector for MudDropContainer and MudDropZone in xmldocs.

The function of ItemSelector is to determine whether an item is within a MudDropZone from its parents MudDropContainer's Items collection.

I believe this is a correction of a copy n paste from the CanDrop function.
