| * 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.␊ |
