Check Page and Count parameters

[kennyctran]

When clients send Page and Count parameters, add the ability to check if the parameters sent are valid. If not, throw an error.

Could you think of a design pattern to validate all incoming parameters? Maybe some middleware that validates by type and could be added to each route applicable.

@trentgoing That would definitely clean up my controllers. I'll look into abstracting current code into middleware as well as adding future parameter checks as middleware.
