examples: directory structure
When generating the gallery automatically, the structure of the examples was not the same for all the modules. This reorganization was made under the following assumption: An example requires: - its own directory, - a '.pyproject' file, - one or more '.py' files, - extra files (likes images, .rc, .ui, etc) Even for cases when subdirectories are made to depict categories, like 'widgets/state-machine/...', one directory is required per example. There should not be '.pyproject' files for categories, except for the general 'examples.pyproject' to open all of them. Task-number: PYSIDE-1490 Pick-to: 6.0 Change-Id: Ie690773c816a248016dbebaad90fbb1d1c2aeea5 Reviewed-by: Cristian Maureira-Fredes <cristian.maureira-fredes@qt.io>
