A generic patricia trie (also called radix tree) implemented in Go (Golang).
The patricia trie as implemented in this library enables fast visiting of
items in some particular ways:
1. visit all items saved in the tree,
2. visit all items matching particular prefix (visit subtree), or
3. given a string, visit all items matching some prefix of that string.
This package contains library source intended for building other packages
which use tchap/go-patricia.
