Merge pull request #2 from paulp/pr/runner

Fleshed out runner script.
Redirect debugging output to stderr.

It makes it easier to dump results printed by an aspect to a file.

//CC: @paulp that can let me know if I'm not doing anything stupid
in bash programming (again).
Add TypeCompletionTiming.aj.

Added aspect that collect information about how much time
has been spent calculating types in your Scala program.
Forgot to mention aspect's name in README.md.
Record specific subclass of LazyType when tracing.

This allows us to see if given type is complete by loading a class
or by typechecking a method defined in source code, etc.
Introduce `traceName` field in traces.

This a replacement for lazyTpeClass which is not really neded
and might contribute to class loader leaks.

All we need is some way of tagging traces with names.
Add TypingTiming.aj which already very usable tool.
Mention post-processing tool producing html.
