```
public class PrefixTree
extends java.lang.Object
```
Prefix tree for paths: if you step on a path prefix that exists, you are good to go. This class parses a text file that has a prefix on each line:
- ignored/formatting - each line starting with '#' (hash) or being empty/blank is ignored.
- a path prefix ie "/org/apache/maven".
By default, artifact is allowed if layout converted path of it has a matching prefix in this file.
Example prefix files:

Modifier and Type	Method	Description
`boolean`	`acceptedPath(java.lang.String path)`
`boolean`	`isLeaf()`
`boolean`	`loadNode(java.lang.String line)`	Adds a line to the tree: it parses the URI-path-like element into list of segments `elementsOfPath(String)` cycles over the list, and marks last node added as `leaf=true` if already on leaf node, processing stops (shorter path wins)
`int`	`loadNodes(java.util.stream.Stream<java.lang.String> linesStream)`
