+
+A collection of embedded objects on the same background model. This structure 
+provides a way to update all the stored objects at once.
+
+## Constructor
+
+- `EmbeddedCollection(recipes::Union{<:Function,Vector{<:Function}},bgmodel::DiscreteModel[,φh])`
+
+If provided, `φh` will be used to compute the initial collection of objects. If not provided, 
+the collection will remain empty until `update_collection!` is called.
+
+## API: 
+
+- `update_collection!(c::EmbeddedCollection,φh)`: Update the collection of objects using the level set function `φh`.
+- `add_recipe!(c::EmbeddedCollection,r::Function[,φh])`: Add a recipe to the collection. Update the collection if `φh` is provided.
