Find number of dimensions and extent along each dimension of
the signal arrays.
- If 0D sqw object, nd=0, sz=zeros(1,0) (nb: []==zeros(0,0))
- if 1D sqw object, nd=1, sz=n1
- If 2D sqw object, nd=2, sz=[n1,n2]
- If 3D sqw object, nd=3, sz=[n1,n2,n3] even if n3=1
- If 4D sqw object, nd=4, sz=[n1,n2,n3,n4] even if n4=1
The convention is that size(sz)=1 x ndim
>> [nd,sz]=dimensions(w)
