Update README with loki> examples

[shakthimaan]

I was able to start the lokijs-server and run the lokijs-client. But, I am not sure how to use the prompt interface.

I tried:

loki> OP_INSERT "name" "foo"

and the lokijs-server crashed with:

{"collection":"\"name\"","obj":"foo"}
Result is undefined
net.js:625
    throw new TypeError('invalid data');
    ^

TypeError: invalid data
    at Socket.write (net.js:625:11)
    at Socket.<anonymous> (/tmp/lokijs-server/server/server.js:40:12)
    at emitOne (events.js:77:13)
    at Socket.emit (events.js:169:7)
    at readableAddChunk (_stream_readable.js:153:18)
    at Socket.Readable.push (_stream_readable.js:111:10)
    at TCP.onread (net.js:531:20)

If you can update the README.md with few examples, it will helpful. Thanks!

it's been ages since i was working on this but i think the last parameter should be a JSON object (instead of "foo"), e.g. loki> OP_INSERT "name" {"foo":"bar"}

That exits the server with a different error ("Result is undefined"):

$ node index -p 47134 -f /tmp/lokijs.log
{ port: '47134', filename: '/tmp/lokijs.log' }
ENV NODEJS
Listening to 47134
{"collection":"\"name\"","obj":{"foo":"bar"}}
Result is undefined
net.js:625
    throw new TypeError('invalid data');
    ^

Any other suggestions on this?

@shakthimaan I will try and look at this today - will update later.

Thanks! I can help in testing the same.

@techfort Have you had time to debug this?

loki> {"status":"ok","message":"collection created"}
loki> insert "collectionname" {"objectname": "test"}
loki> {"objectname":"test","id":null,"objType":""}
loki> create_collection "collectionname" {"objectname": "test1"}
loki> {"status":"ok","message":"collection created"}
