Implemented simple filter 

Greetings!

My Name is Jurjiu Catalin George, I am an aspiring student for working on this project, as part of the Google Summer of Code 2013 program. 

I forked the ArrayExplorer repo and implemented a simple filter for tabular view. The filter should coexist with the highlight feature, but here I implemented this filter instead of the highlight

Sincerely,

Jurjiu Catalin George
