Result record of layer metadata provider search.
The result contains QGIS metadata information and all information that is required by QGIS to load the layer and to filter the results.
The class extends QgsLayerMetadata by adding information taken directly from the provider which is required for filtering (geographic extent) or because the actual values may be different by those stored in the metadata (CRS authid) or totally missing from the metadata (data provider name and layer type).
