[DO NOT CLOSE] remove proposed functionality from directory, etc.

[jGaboardi]

Do not close this issue until transport and locate are back in the package structure.

Per this comment/situation, we should remove the transport and locate directories (and mentions in the docs/README) until functionality is actually present.

remove

• transport directory
• mentions on transport
• locate directory
• mentions on locate

add back once functional

• transport directory
• mentions on transport
• locate directory
• mentions on locate
