 This library calculates the overall priority for a given graph of categorized actionable items, such as features or tasks. It supports any number of actionable item levels, e.g. you can provide an entire range of levels like "Epic", "Story", "Feature", "Task", "Sub-Task", "Step" as input. The main method takes just the top level ("Epic" in this case) and walks through the other children levels automatically.
 
-For example, imagine you have the features "A", "B", and "C". Some of them have 3 tasks "1", "2", and "3". And some of the tasks have subtasks, "x", "y", and "z". So the input is this top level array:

 The simplest way to get the list of tasks in the correct priority order is to just call `sorted()` on the outputs as `ActionableOutput` is `Comparable`:
 
 ```swift
-let highestToLowestPriorityOutputs: [ActionableOutput] = LaserFocus.prioritizedAtoms(inputs: inputs).sorted()
+let sortedOutputs: [ActionableOutput] = outputs.sorted()
 
-print(highestToLowestPriorityOutputs.map(\.id)) // ["A1x", "A1y", "A2", "A1z", "A3x", "A3y", "A3z", "C", "B2x", "B1", "B2z", "B2y"]

 Note that both the input `ActionableInput` and output type `ActionableOutput` are `Codable` and can therefore be easily read from & written to JSON.
