[Nitro] Request parameters

[Jon A. Lambert]

Since I didn't know how to pass arbitrary number of params as array, I tried 
request parameters.
I was getting an error in my actions concerning the number of parameter, so 
I added a 2nd parameter.  This is what it looks lke

Mapping...
Nitro::Server.map = {
  '/' => ArchiveController
}

Controller has...
  def index(path="",foo="")
   pp path
   pp foo
  end

For:
http://localhost:7777/
Prints:
""
""

For:
http://localhost:7777/?path=
Prints:
"path"
nil

For:
http://localhost:7777/?path=papers
Prints:
"papers"
"papers"

What gives?

Thanks
