File hdfdataset.hh: Should we append in the first dimensions instead of the last? Think about what is better/more performant/ expected by users?
Member Utopia::AgentManager< AgentTraits, Model >::neighbors_of (const std::shared_ptr< Agent > &agent, const double radius) const: This should be parallelized or a lookup-grid should be used to constrain the number of possible neighbors to a smaller number
Member Utopia::CellManager< CellTraits, Model >::entity_pointers_from_ids (IndexContainer &&ids) const: TODO This should move into a common manager base class
Member Utopia::Itertools::adapt_zip (Adaptor &&adaptor, Containers &... containers): Make this work with template template instead of callable
Member Utopia::select_entities (const Manager &mngr, const double p_seed, const double p_attach, const unsigned int num_passes): TODO Could generalize this to all kinds of entities with neighbors.
