from_json()

void JsonItemContainerConverter::from_json	(	const QJsonObject &	json,
		SessionItemContainer &	container
	)

Reconstructs SessionItemContainer from the content of JSON object.

Can work in two modes:

• If SessionItemContainer is empty, the content will be reconstructed from JSON
• If SessionItemContainer contains some items already, they will be populated from JSON. Second mode is used when loading project from disk to allow back compatibility.
