1736!- This subroutine is the interface to restput_real which allows

1738!- The logic we use is still fuzzy in my mind but that is probably
1739!- only because I have not yet though through everything.
1740!-
1741!- In the case iim = nbindex it means that the user attempts
1742!- to project the first dimension of the matrix back onto a 3D field
1743!- where jjm will be the third dimension.
1744!- Here we do not allow for 4D data, thus we will take the first
1745!- two dimensions in the file and require that llm = 1.
1746!- These are pretty heavy constraints but I do not know how
1747!- to make it more general. I need to think about it some more.
