Remove Objective-C method signatures

[louisdh]

Is it ok to remove the old Objective-C method signatures?

e.g. the "- (void) removeCrossings" part in this example:

// 1298
//- (void) removeCrossings
fileprivate func removeCrossings()

Also, what does the number above the signature mean? (1298 in the example above)

Sorry to answer so late in the year. The numbers are actually the original line numbers from the original Objective-C Mac OS source code from Andy Finnell's original project. The Obj-C sig is an aid for searching the original source for the equivalent method.

It may be nice to keep them in for historical reference.
