To support pickling
Warning: This method assumes that the constructor should be defined:
__init__(self, config, version=defaultVersion)
The use of 'config' is effectively set by the registry mechanism.
If additional optional arguments are added, this method should be
overridden to correspond.

Find tracts and patches that overlap a region

@return list of (TractInfo, list of PatchInfo) for tracts and patches that contain,

@warning this uses a naive algorithm that may find some tracts and patches that do not overlap
the region (especially if the region is not a rectangle aligned along patch x,y).
