/**
* a graph (or tree) structure that can be executed.
*
* Purpose
*
* ProcessDefinition is a base implementation that can be leveraged to build
* graph based execution languages. While the ProcessDefinition class is
* concrete and can be used as-is (e.g. by aggregation), most likely
* processDefinition languages will inherit from this ProcessDefinition and
* create more specialized implementations.
*
*
*
* The specialized processDefinition language classes can extend this
* ProcessDefinition with new datastructures relevant for that perticular
* processDefinition language.
*
*
* Structure
*
* A processDefinition contains a set of nodes. Nodes can be connected with
* transitions or nodes can have nested nodes. But the transitions and nested
* nodes can be combined.
*
*
* Execution
*
* To create a new execution for a given processDefinition, see
* {@link #startExecution()}.
