/**
* A {@link RefasterRuleSelector} algorithm that selects Refaster templates based on the content of
* a {@link CompilationUnitTree}.
*
* <p>The algorithm consists of the following steps:
*
* <ol>
* <li>Create a {@link Node tree} structure based on the provided Refaster templates.
* <ol>
* <li>Extract all identifiers from the {@link BeforeTemplate}s.
* <li>Sort identifiers lexicographically and collect into a set.
* <li>Add a path to the tree based on the sorted identifiers.
* </ol>
* <li>Extract all identifiers from the {@link CompilationUnitTree} and sort them
* lexicographically.
* <li>Traverse the tree based on the identifiers from the {@link CompilationUnitTree}. Every node
* can contain Refaster templates. Once a node is we found a candidate Refaster template that
* might match some code and will therefore be added to the list of candidates.
* </ol>
*
* <p>This is an example to explain the algorithm. Consider the templates with identifiers; {@code
* T1 = [A, B, C]}, {@code T2 = [B]}, and {@code T3 = [B, D]}. This will result in the following
* tree structure:
*
* <pre>{@code
* <root>
* ├── A
* │ └── B
* │ └── C -- T1
* └── B -- T2
* └── D -- T3
* }</pre>
*
* <p>The tree is traversed based on the identifiers in the {@link CompilationUnitTree}. When a node
* containing a template is reached, we can be certain that the identifiers from the {@link
* BeforeTemplate} are at least present in the {@link CompilationUnitTree}.
*
* <p>Since the identifiers are sorted, we can skip parts of the {@link Node tree} while we are
* traversing it. Instead of trying to match all Refaster templates against every expression in a
* {@link CompilationUnitTree} we now only matching a subset of the templates that at least have a
* chance of matching. As a result, the performance of Refaster increases significantly.
