We want to allow other projects to steal from us, like we stole from
Jupyter/IPython :-). This relicensing / public domain dedication is
possible because all text here is either by me (and thus copyright me)
or else taken from the Jupyter/IPython document, and their document is
also under CC-0 as per https://github.com/jupyter/governance/pull/9

Original text seemed to imply that we would always ask the potential new
Council Member whether they were interested *before* we actually decided
whether to offer them a spot, which could create a sticky situation if
someone ever got voted down.

Rephrase to make clear that things do not have to occur in this order.

In preparation for merging.

Now that this seems to be settled, we don't need this cluttering up the
main text. (For the record: the rule listed here is what we actually
used.)

The 2001 date I had originally was based on the beginning of NumPy's git
history -- but further research suggests that this actually runs back
into Numeric times, before the NumPy project was founded.

New 2005 date is based on Fernando's recollection of the fateful meeting
that led to NumPy's creation, and is consistent with Wikipedia's claim
that 2006 was the first release.

If this is wrong please let me know :-)
