+ContainerUtils
+==================
+
+Helper functions to handle standard container compliant 
+containers. Supports array, vector, sls::Result etc.
+
+While not a part of the public API we aim not to change this
+interface too much. However, we don't give the same strong
+guarantees as for Detector etc. 
+
+Any reoccurring container operation should probably be added to
+this file.
