Change the output of ops.help() to namespaces only

elevans · elevans · commit db287c58acf9 · 2024-04-24T11:46:16.000-05:00
This commit restricts the output of the ops.help() call to
just the namespaces that are available. This changes the
output call from this:

```
   &gt; features.haralick
   &gt; features
   &gt; features.tamura
   &gt; features.zernike
```

to just:

```
   &gt; features
```
