Adding line number of caller

[owentran]

Our team is really enjoying the mock support. Is there a way to get the controller to print the caller class and line number...

For example

--- FAIL: TestGetMany (0.00s)
    controller.go:113: no matching expected call: *lcp_mock.MockOrdersInterface.GetMany([context.Background wpID userID lpID confirmationNumber [statuses] [orderTypes]])
    controller.go:158: missing call(s) to *ids_mock.MockContextService.GetAccessToken(is anything, is anything, is anything)
    controller.go:158: missing call(s) to *lcp_mock.MockOrdersInterface.GetMany(is anything, is equal to accessToken, is equal to userID, is equal to lpID, is equal to confirmationNumber, is equal to [statuses], is equal to [orderTypes])
    controller.go:165: aborting test due to missing call(s)

Instead of controller.go:113 or 158, could the name of the function caller be included in the error message? This would help identify where in the code is actually trying to use the mock.

Thanks for this great library!

There isn't a way, but that's a perfectly reasonable request. I'll see if I can come up with something.

I made #25 to do this.

Actually... it doesn't do exactly what you asked for, but it does add filenames and line numbers to errors, which seems to suffice.

@dsymonds Any progress on this? It would be hugely helpful to see both where an expected call was indicated that did not occur, and where a call was made that was not expected. Either one would be a big win but both would be amazing.

PR #25 was pulled in via #97 so this issue should be resolved. Please re-open if I misunderstood.
