/**
* Allows retrieving the activity instance tree for a given process instance.
* The activity instance tree is aligned with the concept of scope in the BPMN specification.
* Activities that are "on the same level of subprocess" (ie. part of the same scope, contained
* in the same subprocess) will have their activity instances at the same level in the tree.
*
* Examples:
*
* - Process with two parallel user tasks after parallel Gateway: in the activity instance tree you
* will see two activity instances below the root instance, one for each user task.
* - Process with two parallel Multi Instance user tasks after parallel Gateway: in the activity instance
* tree, all instances of both user tasks will be listed below the root activity instance. Reason: all
* activity instances are at the same level of subprocess.
* - Usertask inside embedded subprocess: the activity instance three will have 3 levels: the root instance
* representing the process instance itself, below it an activity instance representing the instance of the embedded
* subprocess, and below this one, the activity instance representing the usertask.
*
*
* Identity & Uniqueness:
* Each activity instance is assigned a unique Id. The id is persistent, if you invoke this method multiple times,
* the same activity instance ids will be returned for the same activity instances. (However, there might be
* different executions assigned, see below)
*
* Relation to Executions
* The {@link Execution} concept in the process engine is not completely aligned with the activity
* instance concept because the execution tree is in general not aligned with the activity / scope concept in
* BPMN. In general, there is a n-1 relationship between Executions and ActivityInstances, ie. at a given
* point in time, an activity instance can be linked to multiple executions. In addition, it is not guaranteed
* that the same execution that started a given activity instance will also end it. The process engine performs
* several internal optimizations concerning the compacting of the execution tree which might lead to executions
* being reordered and pruned. This can lead to situations where a given execution starts an activity instance
* but another execution ends it. Another special case is the process instance: if the process instance is executing
* a non-scope activity (for example a user task) below the process definition scope, it will be referenced
* by both the root activity instance and the user task activity instance.
*
*
If you need to interpret the state of a process instance in terms of a BPMN process model, it is usually easier to
* use the activity instance tree as opposed to the execution tree.
*
* @param processInstanceId the id of the process instance for which the activity instance tree should be constructed.
* @return the activity instance tree for a given process instance or null if no such process instance exists.
