PostCSS plugin to keep rules and at-rules content in order.

	// Nodes for sorting
	let processed = [];

	// Add indexes to nodes
	node.each((childNode, index) => {
		processed = processMostNodes(childNode, index, expectedOrder, processed);
	});

	// Add last comments in the rule. Need this because last comments are not belonging to anything
	node.each((childNode, index) => {
		processed = processLastComments(childNode, index, processed);
	});

	// Sort declarations saved for sorting
	processed.sort(sortByIndexes);

	// Enforce semicolon for the last node
	node.raws.semicolon = true;

	// Replace rule content with sorted one
	node.removeAll();
	node.append(processed);
