Gravity Forms documentation notes that optimum page size is 200 in order to prevent 
database timeouts. If you are expecting lots more than 200 entires (I am planning 
for up to 1000 entries) splitting the returned array may prevent it from happening.
Or not... I literally don't know!  
This will print a maximum of 200 entries.
