 ### The Point
7
+* You are to write a command interpreter using the provided `SimpleShell` class.
8
+* You're going to create a way
9
+	* for commands to be typed into your shell,
10
+	* to read the typed commands and arguments,
11
+	* to send them off to the Under-A-Rock server using a REST API over the HTTP protocol,
12
+	* to read the JSON data returned from the URL call,
13
+	* to print it out nicely formatted for your user.

15
+* `Under-A-Rock` acts a little (very little) like a twitter server or chat server.
16
+	* You register your name and github id by creating an ID JSON payload (see below) and POSTing it to the server.
17
+	* You can GET all the ids registered by sending a GET request to the same URL.
18
+	* Once you've received all the ids, you can send messages to the world or to a specific `Github_id`.

22
-a valid github_id in the "to id" field of the JSON payload, then that message is addressed to that friend. Yes, all 
23

-When you send a new Message or Id JSON object to the server, it records it, and fills in one or two fields. 
26
-A Message gets an assigned sequence number and a timestamp of when it was received by the server. An ID
27

28
-Any sequence number, timestamp or userid you put into a JSON template
29

-You can explore several ways of doing the HTTP URL calls to the server, using the one of these:
41
-* Core Java version 
42
-URL https://docs.oracle.com/javase/8/docs/api/java/net/URL.html and 
43
-HttpURLConnection https://docs.oracle.com/javase/8/docs/api/java/net/HttpURLConnection.html, 
44
-* Apache HTTP Client Library http://hc.apache.org/httpcomponents-client-ga/index.html

47 40
 
48
-Be prepared to defend your choice if which HTTP client library you chose, with reasons why you chose it.
49
-You should also create some unit tests for your REST API handlers. You should look at how ItelliJ does management of
50
-dependencies. (You'll be modifying the `pom.xml` file.) Usually, you merely need to add a `dependency` clause to the `dependencies`
51
-clause in the pom.xml.

-Jackson can help you parse the json into objects,and objects back into JSON strings. Be sure to research how you can
