## Detailed Description

The IAlgResourcePool is the interface for managing algorithm instances, in particular if clones of the same algorithm exist.

It as well manages the shared resources between different algorithms and ensures that not two algorithms with the same non-thread-safe resource needs are made available. The actual creation and deletion of algorithm instances is done through the IAlgManager service.
