Be careful to understand storage ordering and contiguity of the array
when using the data() method in this way. The `isStorageContiguous()'
method is helpful here.
See sections 2.4 and 2.6.2 of the documentation at
http://www.oonumerics.org/blitz/manual/Frames.html
for a discussion of storage orders, indexing, subarrays, and slicing.
