+
+## Client HTTP/REST API for UnderARock
+
+
+### The Point
+
+You are to write a command interpreter using the provided SimpleShell class. You're going to create a way for 
+commands to be typed into your shell, read the typed commands and arguments, send them off to the Under-A-Rock 
+server using a REST API over the HTTP protocol, read the JSON data returned from the URL call, and print it out 
+nicely formatted for your user. 
+
+Under-A-Rock acts a little (very little) like a twitter server or chat server. 
+
+You register your name and githubid by creating an ID JSON payload (see below) and POSTing it to the server. You can GET 
+all the ids registered by sending a GET request to the same URL. Once you've received all the ids, you can send
+messages to the world or to a specific Github_id.
+
+You 
+can send a message to the global timeline by POSTing a Message JSON object to the URL below.
+If you leave the "to id" field empty, the message is "to the world". If you fill out the the JSON template with
+a valid github_id in the "to id" field of the JSON payload, then that message is addressed to that friend. Yes, all 
+messages can be seen by users of the system. There are JSON templates below for both Ids and Messages.
+
+When you send a new Message or Id JSON object to the server, it records it, and fills in one or two fields. 
+A Message gets an assigned sequence number and a timestamp of when it was received by the server. An ID
+object gets a "user id" field assigned to it.
+Any sequence number, timestamp or userid you put into a JSON template
+gets overwritten by the server when you POST it. 
+
+You're going to create a series of REST API handlers that will each perform a 
+specific command. Each one of the command methods will then call a even lower-level method that makes a certain kind
+of HTTP request (GET, POST, PUT) to specific filled-in URL.
+
+The Under-A-Rock Server can be reached at `http://zipcode.rocks:8085` Everyone uses the same server. 
+
+There are two segments to the API and two kinds of commands in the shell, the ID segment and the Messages segment.
+
+
+You can explore several ways of doing the HTTP URL calls to the server, using the one of these:
+* Core Java version 
+URL https://docs.oracle.com/javase/8/docs/api/java/net/URL.html and 
+HttpURLConnection https://docs.oracle.com/javase/8/docs/api/java/net/HttpURLConnection.html, 
+* Apache HTTP Client Library http://hc.apache.org/httpcomponents-client-ga/index.html
+* Unirest for Java http://unirest.io/java.html
+* Square's OKHttp https://github.com/square/okhttp
+
+Be prepared to defend your choice if which HTTP client library you chose, with reasons why you chose it.
+You should also create some unit tests for your REST API handlers.
+
+It's possible you may also need to understand some of what the Jackson package does for you. 
+* jackson json 
+
+## IDs
+
+#### ID commands in shell
+In the shell, 
+`ids` should return a formatted list of the IDs available to you.
+
+`ids your_name your_github_id` command should post your Name and your GithubId to the server.
+If you do this twice with two different Names, but the name GithubId, the name on the server gets changed.
+
+the IDs API is:
+
+#### URL: /ids/
+* `GET` : Get all github ids registered
+* `POST` : add your github id / name to be registered
+* `PUT` : change the name linked to your github id
+
+json payload for /ids/ - this is a sample
+```json
+{
+    "userid": "-", // gets filled w id
+    "name": "Kris",
+    "githubid": "xt0fer"
+}
+```
+ 
+ #### Example: 
+ 
+ if I type 
+ ```aidl
+cmd?
+ ids Kris xt0fer
+```
+  into the shell, your command processor creates a JSON object which looks like:
+ ```json
+ {
+     "userid": "-", // gets filled w id
+     "name": "Kris",
+     "githubid": "xt0fer"
+ }
+ ```
+and send it as the body of a POST request to  `http://zipcode.rocks:8085/ids/`
+
+ 
+## Messages
+
+#### Message comands in shell
+
+in the shell, 
+* `messages` should return the last 20 messages, nicely formatted.
+* `messages your_github_id` should return the last 20 messages sent to you.
+* `send your_github_id 'Hello World' ` should post a new message in the timeline
+* `send your_github_id 'my string message' to some_friend_githubid` should post a message to your friend from you on the timeline.
+
+the Messages API is:
+
+#### URL: /messages/
+* `GET` : Get last 20 msgs - returns an JSON array of message objects
+
+#### URL: /ids/:mygithubid/messages/
+* `GET` : Get last 20 msgs for myid  - returns an JSON array of message objects
+* `POST` : Create a new message in timeline - need to POST a new message object, and will get back one with a message sequence number and timestamp of the server inserted.
+
+#### URL: /ids/:mygithubid/messages/:sequence
+* `GET` : Get msg with a sequence  - returns a JSON message object for a sequence number
+
+#### URL: /ids/:mygithubid/from/:friendgithubid
+* `GET` : Get last 20 msgs for myid from friendid
+
+json payload for /messages/ these are samples, one to a specific friend, one to the timeline.
+```json
+[
+  {
+    "sequence": "-",
+    "timestamp": "_",
+    "fromid": "xt0fer",
+    "toid": "kristofer",
+    "message": "Hello, Kristofer!"
+  },
+
+  {
+    "sequence": "-",
+    "timestamp": "_",
+    "fromid": "xt0fer",
+    "toid": "",
+    "message": "Hello, World!"
+  }
+]
+```
+
+#### Example: 
+ 
+ if I type 
+ ```aidl
+cmd?
+send xt0fer 'Hello old buddy!' to torvalds
+```
+  into the shell, your command processor creates a JSON object which looks like:
+ ```json
+  {
+     "sequence": "-",
+     "timestamp": "_",
+     "fromid": "xt0fer",
+     "toid": "torvalds",
+     "message": "Hello old buddy!"
+   }
+ ```
+and send it as the body of a POST request to  `http://zipcode.rocks:8085/ids/xt0fer/messages/`
