Trie

====

Implements:

* A trie, use it like a `map[string]interface{}`.

* A ternary search tree, like a `map[string]interface{}` from which you cannot delete.

* A trieset, use it like a `map[string]struct{}`.

Performance

===========

This benchmarks shows lookups only (`Get`):

| keys | `map[string]bool` | `trie.TernaryST` | `trie.Trie` |
