/**
 * This model contains multiple {@link Node}s, {@link Service}s to sample
 * {@link DataFrame}s that are pushed or pulled from this model.
 *
 * ## Usage
 * ### Creation
 * Please refer to {@link ModelBuilder} for creating a new model
 *
 * ### Pushing and Pulling
 * Pushing or pulling on a model is possible, but only recommended for prototyping.
 * Instead, developers should use a {@link SourceNode} that automatically pushes new {@link DataFrame}s
 * or pushes new frames when receiving a pull.
