CatStruct2

Concatenates Structures (fields each depth are merged)

FinalStruct = CatStruct2(S1,S2) concatenates the structures S1 and S2 into one structure FinalStruct.

The fieldnames at each depth will be compared. In case the field name is found in both structures, the second occurence will overwrite the value of the first.

CatStruct2(S1,S2,'sorted') will sort the fieldnames alphabetically after merging the two structures.
