function Block::getChildren

Allows an array of "child blocks" for display in the "Add Block" dialog.

This allows a single entry in hook_block_info() to provide multiple block instances displaying different fields.

Note that this function may return NULL or an empty array, which have different meanings. NULL means that a block does not provide children at all. An empty array means that a block may provide children, but that there are none currently.

Return value
