### What is this PR for?
Currently a paragraph can display only a single type of result.
For example
```
print("""
%text textout
%html htmlout
""")
```
will display only last display system detected, "htmlout".
This pr implements multiple results supports, so not only the last, but also all the display systems in a paragraph outputs can be displayed.
To do that, Note.json format need to be changed. from
```
paragraph : [
{
result : {
code: "",
type: "",
msg: ""
},
config : {
graph : {},
...
},
...
},
...
],
...
```
to
```
paragraph : [
{
results : {
{
code: "",
msg: [
{
type: "",
data: ""
},
{
type: "",
data: ""
},
...
]
},
config : {
results : [
{
graph : {},
},
{

Zeppelin Web Application
This is Zeppelin's frontend project.
Development Guide
Packaging
If you want to package the zeppelin-web only, simply run this command in this folder.
This will download all the dependencies including node (the binaries in the folder zeppelin-web/node)
$ mvn package
Local Development
It is recommended to install node 6.0.0+ since Zeppelin uses 6.9.1+ (see creationix/nvm)
All build commands are described in package.json
# install required depepdencies and bower packages (only once)
$ npm install
# build zeppelin-web for production
$ npm run build
# run frontend application only in dev mode (localhost:9000)
# you need to run zeppelin backend instance also
$ npm run start
# execute tests
$ npm run test
Troubleshooting
Git error
In case of the error ECMDERR Failed to execute "git ls-remote --tags --heads git://xxxxx", exit code of #128
change your git config with git config --global url."https://".insteadOf git://
Proxy issues
Try to add to the .bowerrc file the following content:
"proxy" : "http://<host>:<port>",
"https-proxy" : "http://<host>:<port>"
also try to add proxy info to npm install command:
<execution>
<id>npm install</id>
<goals>
<goal>npm</goal>
</goals>
<configuration>
<arguments>--proxy=http://<host>:<port> --https-proxy=http://<host>:<port></arguments>
</configuration>
</execution>
and retry to build again.
