Seems to work for Node right now. I haven't tested on linux.

Rename file namespaces to rekord

Simple fix for hardcoded filename

Get Leaf command

Capture case of no previous state file present

Gets a specific leaf by the leaf Index

`rekor getleaf --index ($index)

Based on comment in PR #19

Add an update command to fetch and store the latest rootTreeHash/Size.

If we have a previous set of values, we also check the consistency proof between
these two to make sure the tree has not been tampered with.

General clean up

* Remove unsed files (log_server, inclusion (which is now get)

* Add some meaningful text to CLI help

* Make the README more specific to the new role of the CLI (direct
connections to rekor server)

Proof

Switch the get command over to use the server, and refactor a bit.

Hook these up to the server instead of the trillian DB.

Basic CI Setup
