Computes the hyperbolic distance between a point at polar coordinates (ZI$r, ZI$theta) and m points at polar coordinates (ZJ$r, ZJ$theta).

1	hyperbolic_dist(ZI, ZJ)

`ZI`	single-element data frame; A node in hyperbolic space placed at polar coordinates (`ZI$r`, `ZI$theta`).
`ZJ`	data frame; m entries representing m nodes in hyperbolic space placed at polar coordinates (`ZJ$r`, `ZJ$theta`).

An m-element vector with the hyperbolic distance between node ZI and nodes ZJ.

# Generate an artificial network with the PS model
net <- ps_model(500, 6, 2.5, 0)
# If nodes data frame contains m nodes, use the following 
# to compute the distance between node 1 and the rest (including itself):
nodes <- net$polar
d <- hyperbolic_dist(nodes[1,], nodes)
# To compute the pairwise distances between m nodes use:
D <- sapply(seq(nrow(nodes)), function(i) hyperbolic_dist(nodes[i, ], nodes))
