Figure out solution to 0 arg methods

[nathanclevenger]

Can we try to get this: http://lodash.do/values/shuffle/take/10/vehicles.do/random-vins.json

to work this does: http://lodash.do/values/_/shuffle/_/take/10/vehicles.do/random-vins.json

It messes up the current logic that's used, but the first syntax is much more elegant

The solution I came up with was to get the function signature by calling .toString() on the Lodash function itself. Then, using regex, I got the list of arguments and subtracted one, since they always require at least one arg (the list). If the remaining count is 0, then the function takes no arguments we also take only one from the pathSegments array.
