This is a library for translate a UTF-8 string to/from a pairtree notation. This is typically used in storing things on disc (e.g. repository filesystems). This code is based on the specification found at https://confluence.ucop.edu/download/attachments/14254128/PairtreeSpec.pdf?version=2&modificationDate=1295552323000&api=v2 which is cited on the OCFL wiki.

• Set() will let you set the path separator
  • Separator is a readonly value of the file separator used by Encode() and Decode()
• Encode() will encode the provided string as a pairtree path
• Decode() will decode a pairtree path returning the unencoded string
