An SBN river network as a downstream directed igraph object.

1	sbn_create(n, p)

`n`	desired number of nodes.
`p`	branching probability, from 0 - 1. Passed to `stats::rbinom()`, the probability of success in two attempts at adding upstream branches.

SBNs are generated using a stochastic branching process. The network generation process starts from an initial downstream node (the river mouth). At each iteration a random node in the network, with no upstream connections is selected, and zero, one or two nodes are added upstream of it, depending on a branching probability (p). This process is repeated until a pre-determined number of nodes across the entire network is attained (n).
