/**
* Class that calculates the activity value for all projects on a
* specific date and time.
*
* We do this by counting adds or updates of database objects in
* the particular section (according to the timeline) and relate this
* value to the overall activity of a section in the forge.
*
* To illustrate the behaviour, a simple example could be a forge with
* only two projects that both have only issue tracking enabled.
* The first project created or updated 10 tickets during the past period,
* the other 20. The activity index for the first should therefor be
* calculated as 0.33 and the second as 0.66.
* Note that this simple example doesn't take activity in other
* sections into account, so the the total activity of all projects
* for a certain time period might add up to more than 1.0.
