Modified the calculation engine to extrapolate usage values and timestamps before start usage / start date (previously this caused an error). An example is calculating the usage amount of a Work Order with a date before the Asset Start Date.
Task Management Pages
Fixed an issue calculating Due Δ and Due Δ % for tasks that had no previous Work Order and where the Asset's start usage was non-zero.
Include Next (usage amount of the next occurrence) on the Task Management pages.
Calculate Last Done Date and Next values for calendar-based tasks.
The export feature on the Task Management pages now exports all columns displayed on the page and all rows that match the filter selections. Also modified the export to run asynchronously.
