Revert "refined data to companies less than 500 employees and more than ...

Hi Andy,

I took longer than I was supposed to. Frankly, I spent too much time trying to find a query that would give me all the data I needed (i.e. the # of employees and date founded). I realized all too late that I needed to do a specific API request for each company to get the specific data needed to filter the company list. 

Overall, the app would probably be much more elegant using Javascript and ajax methods. Under the time constraints I kept to PHP. It's not pretty, but it works. Now that I understand the CrunchBase API, I'm sure I could do this much more quickly. 

Take a look and let me know what you think. Whether or not you choose to hire me I would greatly appreciate your feedback. 

Thanks!
