Feature: drive clusters with external dataset#19
Merged
Conversation
Introduce DatasetPickerAction and DimensionPickerAction to SettingsAction: add header includes, new member variables and getters, initialize them in the constructor, set the dataset picker as Clearable, and add both actions to the UI layout (reordering the AlgorithmAction accordingly). These allow selecting an external dataset to optionally merge with clusters and choosing a dimension for processing.
Enable OpenMP in CMake and link it when found. Add support for selecting an external points dataset in the IdentifierExtractor settings (migrate settings UI to a VerticalGroupAction and add a DatasetPickerAction) and make Extractor::getInputDataset virtual with an override to prefer the external dataset when present. Parallelize IdentifierExtractor::extract using OpenMP: build per-thread maps of clusterID -> point indices, merge them, sort cluster keys and construct Cluster objects. Also add required includes and remove the now-unneeded external/dimension actions from the global SettingsAction.
Added a tutorials section with an image and description.
