/* Note about the project tree build process:
 * Building the project tree can be *very* long if there are a lot of subdirectories in the
 * working directory.  Unfortunately, this happens easily if the project file *.pro is in the
 * user's home directory.
 * So the tree project is built "on demand":
 * First the tree is built from the current directory and shows files and subdirs.
 *   > First level subdirs trees are built (i.e subdirs contents are not read)
 *   > When expanding a subdir, each subdir contains is read, and the corresponding sub tree is
 *     populated on the fly.
