PR #941 - Improved Age Stats gramplet

I have been working on an improved Age Stats gramplet in pull request #941.

See screenshot below:

It has similar functionality to the old gramplet. Hovering over a bar highlights it. Double clicking on a bar shows a quick report of the people within the selected range.

I have added an orange bar for values exceeding the maximum range set in the configuration. The chart also automatically resizes.

Any comments and suggestions are welcome.

Perhaps we should separate the charts into separate gramplets? Would some pie charts be useful?

Oh I like that! Do the age stats include living people, or just those with dates of death?

Phil.

The lifespan chart only includes people with a death event, but the parent-child age difference charts include living people.
