Good point! I'd try to stay "integer counter" internally/for the ctor, but offer alternative `make` signatures, one with the maximum number of items, but another convenience one that converts time...

@mormj I came at it from the Qt Time Sink side, where you do specify the number of samples. But let me quickly remedy that by simply introducing the steps...

@dkozel it is annoying, but I can't have a single backwards-compatible block; GRC doesn't support ignoring unknown parameters from a GRC file. So, I'll have at least two blocks (classic...

This still needs a test case and wiki page before of can be merged. C++ gen is completely untested!
