reader: remove JavaScript client
Remove the JavaScript client for the Reader app, and also modify
vanadium-reader-test so that it runs the Gradle java test instead of
Makefile.

+# Cloudsync for Reader
+
+This directory contains scripts for building and running the Cloudsync instance,
+which is a Syncbase instance which hosts the syncgroup and replicates the data
+of all the Reader app clients for a user. There must be a Cloudsync instance
+running for the Reader app to work properly.
+
+For now, every user needs to have a separate Cloudsync instance running, but
+this requirement may change in the future. To learn more details about Syncbase,
+please refer to its [website](https://vanadium.github.io/syncbase).
+
+# Development
+
+## Dependencies
+
+To build the binaries for Syncbase, you need to have the base profile installed
+with `jiri` tool with the following command:
+
+ jiri profile-v23 install v23:base
+
+## Running Cloudsync
+
+To run the syncbase instance which hosts the syncgroup:
+
+ make cloudsync
+
+This will run a cloudsync instance that will mount as
+`users/<email>/reader/cloudsync` and host the syncgroup. In order for peers to
+sync an instance of this needs to be running somewhere.
+
+To run a new cloudsync with a different port number:
+
+ port=8888 make cloudsync
+
+This will automatically have you set up credentials etc. If you want to remove
+stored data & credentials use:
+
+ make clean

-# Development
-
-## Dependencies
-
-If you have a `$JIRI_ROOT` setup you can install Node.js from
-`$JIRI_ROOT/third_party` by running:
-
- jiri v23-profile install nodejs
-
-Optionally, it is possible to use your own install of Node.js if you would like
-to use a more recent version.
-
-## Building
-
-The Makefile is setup to handle all dependencies once Node.js is installed. The
-default make task will install any modules listed in the `package.json` and
-build a browser bundle from `browser/index.js` via browserify.
-
- make
-
-It is possible to have the build happen automatically anytime a JavaScript file
-changes using the watch tool:
-
- watch make
-
-## Running locally
-
-To run a local dev server use:
-
- make start
-
-If you would like to change the host and or port that is used:
-
- make start port=<port> host=<host>
-
-Run syncbase with:
-
- make syncbase
-
-Run the syncbase instance which hosts the syncgroup:
-
- make cloudsync
-
-This will run a syncbased instance that will mount as
-"users/<email>/reader/cloudsync" and host the syncgroup. In order for peers to
-sync an instance of this needs to be running somewhere.
-
-To run a new syncbase peer and corresponding application use variables to change
-the startup settings:
-
- syncbase_port=8888 id=`./bin/cuid` make syncbase
-
-This will generate a new client id and start a new syncbased instance on a
-different port. The generated id can be grabbed from the standard out and will
-look something like this "cif7en1kb00007uigyohv58tx". Once you have the id you
-can open a new browser window and use the id in a query param to initialize the
-application to connect as that peer.
-
- http://127.0.0.1:8080/?id=<id>
-
-This will automatically have you set up credentials etc. If you want to remove
-stored data & credentials use:
-
- make clean

-//
-// A virtual-dom widget for creating and managing a canvas element which is
-// optimized for high density displays. The constructor takes two arguments:
-//
-// * draw: Function - called every update/render, the function will be called
-// with the arguments `context`, `state`, and `done`.
-// * state: Object - the
-// state object passed in during virtual-dom creation
-//
-// This widget is optimized for usage with PDF.js which has an async render
-// method. Render updates can happen at about 60 fps so some book keeping needs
-// to be done to queue PDF.js render calls to prevent multiple renders from
-// happening simultaneously (triggering weird pdf render bugs like upside down
-// text etc.). The queueing mechanism is simple but requires the `draw` function
-// to fire a callback when it's work is done.
-//
-// Example:
-//
-// var state = {
-// width: window.innerWidth,
-// height: window.innerHeight,
-// ratio: window.devicePixelRatio
-// }
-//
-// h('.pdf-viewer', [
-// canvas(draw, state)
-// ]);
-//
-// function draw(context, state, done) {
-// // Simulated async method which draws to the canvas context.
-// setTimeout(function(){
-// ctx.fillStyle = 'rgb(200,0,0)'
-// ctx.fillRect(10, 10, 55, 50)
-// done()
-// }, 120)
-// }

- *
- * NOTE: It provides protection from circular references by keeping track of
- * of loaded references. However, you must be careful not to load any graphs
- * that have references to the catalog or other pages since that will cause the

- * CharStrings are encoded following the the CharString Encoding sequence
- * describe in Chapter 6 of the "Adobe Type1 Font Format" specification.
- * The value in a byte indicates a command, a number, or subsequent bytes
- * that are to be interpreted in a special way.
- *
- * CharString Number Encoding:
- * A CharString byte containing the values from 32 through 255 inclusive
- * indicate an integer. These values are decoded in four ranges.
- *
- * 1. A CharString byte containing a value, v, between 32 and 246 inclusive,
- * indicate the integer v - 139. Thus, the integer values from -107 through
- * 107 inclusive may be encoded in single byte.
- *
- * 2. A CharString byte containing a value, v, between 247 and 250 inclusive,
- * indicates an integer involving the next byte, w, according to the formula:
- * [(v - 247) x 256] + w + 108
- *
- * 3. A CharString byte containing a value, v, between 251 and 254 inclusive,
- * indicates an integer involving the next byte, w, according to the formula:
- * -[(v - 251) * 256] - w - 108
- *
- * 4. A CharString containing the value 255 indicates that the next 4 bytes
- * are a two complement signed integer. The first of these bytes contains the
- * highest order bits, the second byte contains the next higher order bits
- * and the fourth byte contain the lowest order bits.
- *
- *
- * CharString Command Encoding:
- * CharStrings commands are encoded in 1 or 2 bytes.
- *
- * Single byte commands are encoded in 1 byte that contains a value between
- * 0 and 31 inclusive.
- * If a command byte contains the value 12, then the value in the next byte
- * indicates a command. This "escape" mechanism allows many extra commands
- * to be encoded and this encoding technique helps to minimize the length of
- * the charStrings.
