Function baxterClones

baxterClones(
    trees: readonly CloneTree[],
    config: BaxterConfig,
): {
    comparisons: number;
    pairs: { a: SubtreeRef; b: SubtreeRef; similarity: number }[];
    subtrees: number;
}
The basic algorithm of Baxter et al., "Clone Detection Using Abstract Syntax Trees" (ICSM 1998): subtrees of at least massThreshold nodes are bucketed by their shape (ignoring the lexemes of leaves) and compared within their bucket. Buckets are processed by decreasing mass, so a pair is skipped if a member lies within a member of a pair accepted before (the paper removes such pairs afterwards). Roots of files and pairs of a subtree with its ancestor are skipped.
Parameters
- trees: readonly CloneTree[]
- config: BaxterConfig
Returns {
    comparisons: number;
    pairs: { a: SubtreeRef; b: SubtreeRef; similarity: number }[];
    subtrees: number;
}
Example
```
const { pairs } = baxterClones(index.files.map(f => cloneTree(f, index.perspective)), { massThreshold: 30, similarityThreshold: 0.9 });
```
