[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

• [x] transport directory
• [x] mentions on transport
• [x] locate directory
• [x] mentions on locate

add back once functional

• [ ] transport directory
• [ ] mentions on transport
• [x] locate directory
• [x] mentions on locate
