To prepare the migration to 3.0, we need to change the location where the documentation is generated from.
Having a gh-pages branch makes it hard to synchronize the code and the docs. Having a "docs" folder in the repo itself simplifies this.
Removed the `ReaderEntityFactory::createReader(Type)` method and replaced it by 3 methods:
- `ReaderEntityFactory::createCSVReader()`
- `ReaderEntityFactory::createXLSXReader()`
- `ReaderEntityFactory::createODSReader()`
This has the advantage of enabling autocomplete in the IDE, as the return type is no longer the interface but the concrete type. Since readers may expose different options, this is pretty useful.
Similarly, removed the `WriterEntityFactory::createWriter(Type)` method and replaced it by 3 methods:
- `WriterEntityFactory::createCSVWriter()`
- `WriterEntityFactory::createXLSXWriter()`
- `WriterEntityFactory::createODSWriter()`
Since this is a breaking change, I also updated the Upgrade guide.
Finally, the doc is up to date too.
Add `WriterEntityFactory::createWriterFromFile`, working like `ReaderEntityFactory::createReaderFromFile` (guessing writer type from file name).
Use static functions when needed.
