Create and query blk nodes

• blk_new() instantiates a new blk node.

• blk_type() checks if the node is a blk node.

• blk_<child>_get() returns the <child> node of blk.

• blk_<child>_set() sets the new <child> and deletes the old <child>.

• blk_<child>_rep() sets the new <child> and returns the old <child>.
