Ah yes, that would be a good idea. In fact, one of my "top ten"
requests was to have all of the functions that accept dimensions,
accept them in a consistent way. REBIN, REFORM and TOTAL are all
different. We should be able to specify dimensions consistently
between them, and either as an array, or a list of scalars.

Here is my entry. Sorry, no HISTOGRAM call, but I need to give it a
rest once in a while.

nel = dims(0)
for i = 1L, n_elements(dims)-1 do nel = nel * dims(i)
arr = reform(findgen(nel), dims)
