Nested arrays can be used to crash node.

This may be the same as issue #28 but the parser will create a new array if the parameter looks like: foo[0]=bar. Taking that a step farther foo[0][100000000]=bar will create an array with an array of null objects at the first index of the object. Any time the server tries to perform an action on this object the process runs out of memory and crashes.

I'd suggest range checks be performed before the creation of the query string parameter object, or cap the size of the parameter object.
