…uence, which gives it most of the standard methods found on list.

I also went ahead and added a reverse method, which for some reason is not on the MutableSequence abstract class.
This made it a lot easier to teach others how to work with the collections, as they could just reuse what they knew about manipulating lists.

The original API was left in place, and all tests continue to pass.

Also extended the API of BoundCollection by inheriting from Sequence, which makes it more tuple-like.

…llback instead of an attribute. Had to special case it in the helpers/tools.py module so that regenerating the controls won't reintroduce the bug.

… of None. This fixes an issue when trying to bind the property when empty.

Forgot to include this last night.
Added a test for the new reverse method, and updated the sort test to have unsorted content at the start, and actually call the primary sort method before calling with the reverse flag.

Instead of special special casing 'alwaysInvokeEnterCommandOnReturn', this adds an explicit callback_exceptions set. Which means when Autodesk adds another conflicting name we can just extend the set.

Extends the API of ObservableCollection by inheriting from MutableSequence

Changed how the exiting context manager determines the new parent layout

… broken by new inheritance chain

Noticed that forms had an an __all__ attribute but lists and gui did not.
gui's is using the __lookup.values() as it's reference, seemed much simpler than copy and pasting all the strings.

Adding __all__ to lists.py and gui.py

Updated to use the new keyless syntax.

Moved the bindings operations to separate lines, mostly to make them a bit more visible.

Fixed some child count errors in a few of the examples.
Swapped the loops that needed a counter over to using `enumerate()`
Added a new global example that lets you trigger all the others.

Updated to use the new keyless syntax.
Tweaked the imports so it doesn't flood the local namespace anymore, instead I'm relying on the various modules' `__all__` attributes.
Cleaned up the imports so they're all at the top of the module.

Updated to use the new keyless syntax.
Changed the filter to using a nested function instead of the eval / lambda combo, which was throwing silent errors before.
Moved the binding operations to their own lines.

Updated slightly to use the keyless syntax.
Some minor naming tweaks.
Refactored the imports to not use `import *`

Updated to use new keyless syntax.
Fixed some issues with the module parsing if a module used MAYAVERSION or LOCALE.
Used python to get the MAYA_MODULES_PATH env instead of calling into mel, also tweaked some of the path handling to use python constants.
Put a fallback on the module edit button, so if the os can't determine an editor for .mod files, it uses notepad on windows, and vi everywhere else, hopefully.

…proxy doesn't work...?) which simplifies the public face

Avoids a case where the reference to the parent is lost while inside the
context manager.
