added templating for debug #11

I really like the idea of the package. I was just missing a way to include the value of variables in the output. Therefore I've patched debug() to retrieve variables for placeholders from the parent environment.

It should now be possible to do stuff like this:

path = file.path(tempdir())
ok = dir.create(file.path(path, "mydir"))
"!DEBUG Created directory {{path}}: {{ok}}"
"!DEBUG Files in {{path}}: {{length(list.files(path))}}"

Thanks!

It is not very well documented, but I actually implemented this already, almost the same way as you, but using backticks: https://github.com/gaborcsardi/debugme/blob/543ea249b3eb3fd0e2031ba93e44a24356ba1aaf/R/instrument.R#L31

Oh damn. I should RTFM first. I'll close then.

Or ask quickly, because I might be working on it already.... Hopefully it was not too much work....
