Each node has a unique address, and you set that up according to the info above, so the root node is Octal0
O for octal (base 8 where 8=O10).
they are in a tree structure, and each node can have upto 5 children (nodes hanging directly off the same parent)

}
setup begins the network on channel 90 and includes the node 'this_node' which was declared and assigned by,
const uint16_t this_node = 0; // Address of our node
so each node is attached to an arduino and as they start up and run each one shouts out here i am number X on channel 90... 
the actual checking and processing of the trafic is done by executing the RF24Network::update() command
on the board attached to each node, so if u have a message to send to node Y send it using RF24Network::write() and trust to the network gods ;).. Or dig deeper..
beyond which i cant help much as i am not using these in my project and i still have my own homework to do. Im not using such well documented libs with some of my selected h/w
if you still dont get it either use the examples to knock up a 3 none network with lots of embedded serial writes so you can track what and how the code flows.
Or try asking specific questions..
remeber when using a library with little or no documentation you can always look in the .h file for all the public declarations and probably a good explaination as to whats what.
** edit, perhaps you dont get how the network knows how to direct the traffic 'undr the hood', thats down to the trees structure of the nodes and the known addressing format 1 parent/5 children and octal addressing protocol..
