Transforms the event log to an interval tree using one of the available variants
Parameters
-----------------
log
Event log
variant
Variant of the algorithm to be used:
- Variants.OPEN_PATHS: transforms the event log to an interval tree in which the intervals are the
directly-follows paths in the log (open at the complete timestamp of the source event,
and closed at the start timestamp of the target event),
and having as associated data the source and the target event.
Returns
-----------------
tree
Interval tree object (which can be queried at a given timestamp, or range of timestamps)
