Update version in README
Hi,
i took the version (0.0.2) from the README.md, after compiling and running my project i got an error regarding non-existing file, i searched through issues, i found the PR that fixed that, i then checked out the newest version on crates.io and finally installed 0.0.3 which works just fine.
I'd suggest bumping the version in the README file to avoid confusion for other people. Do you want to open a PR about that, or would you rather do that yourself?
Btw i find your crate immensely helpful in my current project :)
No function names in results (on OS X)
Hi!
I'm trying to get this working on OS X 10.11.6. It seems to build and work, but no function names are included in the results. Everything is collapsed under mandelbrot as a single entry (see below).
Any way to use this on OS X, or is it Linux only?
Thanks!

Profiling fails is profile file does not exist
PROFILER.lock().unwrap().start("/tmp/prof.profile").unwrap();
[...code...]
PROFILER.lock().unwrap().stop().unwrap();The above code fails with "No such file or directory" if the /tmp/prof.profile file does not already exists. This strikes me as poor usability; the file should be created if it doesn't exist and overwritten if it does.
