Change "observations" to "features" in description of LassoLarsCV (#8362)

Charlie Brummitt · agramfort · commit 3d5773027ed7 · 2017-02-15T17:48:25.000Z
The description of LassoLarsCV compared the number of samples with the number of observations, but it was meant to compare the number of samples to the number of features (or dimensions) of the data. I changed "observations" to "features" in the following sentence:
&gt; However, :class:`LassoLarsCV` has the advantage of exploring more relevant values of `alpha` parameter, and
if the number of samples is very small compared to the number of observations, it is often faster than :class:`LassoCV`.
