Allow to rename an uncompressed directory

[Raul Fraile]

The library should allow to rename an uncompressed directory. Now, if compressedDir.tar.gz contains a directory called foo and is uncompressed in target, the final result will be:

$distill->extract('compressedDir.tar.gz', 'target');
// target/foo/[files]

There should be a third option to change the name, so the final result would be:

$distill->extract('compressedDir.tar.gz', 'target', true);
// target/[files]

I'm not an expert on "clean code", but they usually say that boolean arguments are bad for functions. What about creating a new method called extractAndMove() or extractToTarget() or something like that?

@javiereguiluz agreed

@javiereguiluz v0.7 includes a new method for this: extractWithoutRootDirectory. Could you check? It accepts the same parameters as extract.
