Simple benchmark utility

The benchmark runs a "workflow tree" made up of root, mid and leaf workflows. The root workflows start mid workflows, which in turn start leaf workflows. The leaf workflows execute activities.

Options to influence the number of workflows, sub-workflows, and activities:

• -runs Number of root workflows to start
• -fanout Number of child "mid" workflows to execute per root/mid workflow
• -leaffanout Number of leaf workflows to execute per mid workflow
• -depth Depth of mid workflows
