Compare elements in trieSeq by using "<" instead of "<=".
Use binary-search to find next child node instead of linear-search.
Copy the framents of a key only in patriciaTrie.insert.
If insertion occurs, findNode returns the new node inserted to trie.
Replace "getPrefixWith" with "prefixSizeOf". Not the common prefix but its lenght is needed.
