Subject: [PATCH 03/10] Add timestamp to AnalyzedSeries

This can be used to compare whether an AnalyzedSeries object is more
recent than the set of change points it was computed from. (Think
cache invalidation, even if the AnalyzedSeries isn't necessarily a
cache.)

Subject: [PATCH 05/10] Fix: When computing weak changepoints, keep p-value
 below 1

Hunter modified e-divisive such that it first does a pass using a
higher p-value, then filters out all change points that have a
higher p-value than the actual max_pvalue specified by the user.

The initial higher pvalue is max_pvalue * 10. This means that
for values higher than 0.1, the first pvalue is > 1.0. This
doesn't make sense. In fact 1.0 also doesn't make sense because
now every point is a weak change point.

This patch modifies the call to split() such that:
 max_pvalue:   first pass pvalue
 0.0 - 0.05:   max_pvalue * 10 (unchanged)
 0.0 - 0.5 :   max_pvalue * 2
 0.5 - 1.0 :   max_pvalue

Since values above  0.1 didn't really make sense before this patch,
the area where this could cause changes is for users using max_pvalue
between 0.05 and 0.1. The merge() phase should however eventually produce
approximately the same set of change points anyway, but this isn't
guaranteed.

Subject: [PATCH 07/10] Optimization: Incremental Hunter

The common case is to add new data points to the end of the series.
In this case we don't need to recompute all change points, we can
just compute window_len points from the end. We do roughly
2 * window_len for good measure.
