Summary	0002030: Better ordering for readers and CanReadFile
Description	Some readers implement CanReadFile and others do not. Currently if a reader that does not have CanReadFile comes before a reader with CanReadFile it will always be used. Try opening VTKData/Data/teapot.g with the Exodus reader enabled. Selecting a reader should follow steps like this: 1.) Select a set of candidates based on extension. 2.) Call CanReadFile on those that provide it. If any returns non-zero use the first highest return value. 3.) Otherwise use the first reader that does not have CanReadFile. We should also have a better review process for which readers can implement CanReadFile. Since the method has several return values it is sometimes possible to do some preliminary quick checks even if a full CanReadFile cannot be implemented.
