.. now has an overlay widget that can contain multiple widgets
and is user movable and resizable etc
.. we show the model derived values for now, but could add other
things at a later date (e.g. MU distribution etc).
Fixes#811.
To get the date settings to register user interaction
you needed to restart gc after adding the chart. This
was caused by an initialisation error, setting the active
flag to true on object creation -- it should have been
set to false.
.. added a 'This' option to choose a date range
such as this month, week, year. I also added the ability
to specift a 'prior' period.
So in July you could plot for this month prior 1 to choose
a date range for June.
This allows folks to have a static setup of charts for this
this-1 and this-2 months and data to change over time.
You can now add the summary chart to the diary
view to get a summary of the date range currently
being summarised on that view.
Once the Home view has its own sidebar that selects
date ranges you will be able to add it there too
and summarise seasons etc.
To allow charts to have a property set for the date range
to plot a new property is added. This will work in the same
manner as the "ride" property.
No functional enhancement.
