Directories
Directories in a tome namespace may contain scripts. These scripts can be activated as a sub command of the directory name.
For example, a file "foo" in a directory "dir" can be called as:
tome-command dir foo
Ignoring Directories
Directories can be ignored by adding a .tomeignore file in the directory.
Tab completion of Directories
If one attempts to tab complete a directory, all valid tome scripts and subdirectories will be valid options.
