<p>return the magnitudes of vectors in a rank 1 or greater dataset (typically
rank 2). The last index should be the cartesian dimension. For example,
<blockquote><pre><small>
ds= getDataSet('http://autoplot.org/data/autoplot.cdf?BGSM') # BGSM[Epoch=24,cart=3]
m= magnitude(ds)
</small></pre></blockquote>
For rank 0, this just returns the absolute value, but with the same units.</p>

ds - dataset of Rank N.

<p>Merge the two sorted rank N datasets, using their DEPEND_0 datasets, into one rank N dataset.
If neither dataset has DEPEND_0, then this will use the datasets themselves. When ds1 occurs "before" ds2, then this
is the same as concatenate.
When there is a collision where two data points are coincident, use ds1[j]. This is fuzzy, based on the depend_0 cadence of ds1.
When ds1 is null (or None), use ds2.
