1.0.0

Backward-incompatible changes

• All interfaces have been renamed so that their name ends with Interface to follow an interface naming convention which is predominant in modern PHP.
• rdfInterface\DatasetInterface extends rdfInterface\QuadIteratorAggregateInterface (a strongly-typed IteratorAggregate with an optional filtering) instad of rdfInterface\QuadIteratorInterface (a strongly-typed Iterator) which laregely decouples implementation of the iterator from the dataset implementation.

New features

• Allowing rdfInterface\Dataset::getOffset(0) and rdfInterface\Dataset::offsetExists(0) as a syntax for getting any quad out of a dataset and checking if a dataset is not empty.
  This allows the $dataset[0] ?? $defaultQuad syntax for safely getting a single quad out of a dataset.
• rdfInterface\QuadIteratorAggregateInterface added.
