/*!
Copies the directory specified by \a srcFilePath recursively to \a tgtFilePath. \a tgtFilePath will contain
the target directory, which will be created. Example usage:
\code
QString error;
bool ok = Utils::FileUtils::copyRecursively("/foo/bar", "/foo/baz", &error);
if (!ok)
qDebug() << error;
\endcode
This will copy the contents of /foo/bar into to the baz directory under /foo, which will be created in the process.
\note The \a error parameter is optional.
Returns whether the operation succeeded.
