module avail --no-indepth

Some improvement on the module avail command. It is desirable to only get as result the default available names, not all the fully qualified names.

For instance, if you have a modulefile gcc/6.1.1, only returns gcc.

It should materialize through an option on module avail (something simpler than --i_only_want_to_see_the_default_names of course) and maybe also with an internal flag to set if this should be the default display mode.

This feature simplifies output in case of large modulefile catalog. It should also be used by shell completion scripts as in this case we only need to see the names of the current searching level.

This enhancement may also improve avail performances a bit, but not drastically as when we want to see modulefiles at level 1, it should go down level 2 to check there is at least one modulefile (to ensure directory has module-related content).

DevHints: should adapt findModules and getModules internal procedures to achieve this enhancement.

Maybe an option --show-levels could say how deep you want to display? This may be useful for people using more than one sub-level (i.e. we have tools/gcc/6.1.1 and projects/foo/0.9).

In your example, you would set --show-levels 1 to get gcc returned for gcc/6.1.1; I would set this to 2 to get all tool and project names.

To clarify a bit, the idea is to get available modulefiles found at the same file depth level than the expressed query.

Say for instance we have the following modulefiles:

d
dir/1
dir/2

module avail --no-indepth or module avail --no-indepth d would return:

d
dir/

and modulefile avail --no-indepth dir/ would return:

dir/1
dir/2

@cmarqu: regarding your --show-levels proposal, I would prefer keeping this feature simple for the moment and only proposing a full depth search (with --indepth option, which is the default behavior) and a non-recursive/current depth search (with --no-indepth option)
