sample application showing how to

• make use of kontraktor-http server side html-import polyfill (reduces number of http requests drastically)
• use and organize polymer 1.0x webcomponents with kontraktor's resourcepath
• define custom webcomponents
• integrate existing js (d3 word cloud) by defining a webcomponent + using html imports
• websocket communication of js <=> kontraktor, server push
• create an application specific kson config file

the app computes a word cloud from buzzwords typed in. The more often a buzzword has been typed, the larger the word is rendered (realtime, distributed across all users).
