Constructor of the 'natPosition' class
Translate the vector into a DBN network
Uses this object private cl and transforms it into a DBN.
Add a velocity to the position
Given a natVelocity object, add it to the current position.
Return the static node ordering
This function takes as input a dbn and return the node ordering of the variables inside a timeslice. This ordering is needed to understand a position vector.
Translate a DBN into a position vector
This function takes as input a network from a DBN and transforms the structure into a vector of natural numbers if it is a valid DBN. Valid DBNs have only inter-timeslice edges and only allow variables in t_0 to have parents.
Generates a random position
This function takes as input the number of variables, the maximum size and the parameter p and returns a random position with arcs sampled either from the uniform distribution or from a truncated geometric distribution. Much faster than the binary implementation with lists of lists and random bn generation into translation.

A natPosition represents a single HO-DBN structure with a vector. Its function is to encode the solutions in the PSO framework. Each particle will have a position.
