function uuid_node_features_rebuild_nodes in UUID Features Integration 7

Runs the node import multiple times to resolve dependencies.

We might need several runs of ths function to resolve the dependencies created by reference fields. Those can only be resolved if the target node already exists.

Parameters

array $nodes: The nodes to process.

string $module: The module to rebuild for.

int $max_nesting: Maximal nesting level.

int $nesting_level: Current nesting level.

Return value

bool TRUE if all nodes could be restored.
