Detailed Description

Geometric-bound upper bound on the queue length at station i.

Templated port of matlab/src/api/pfqn/pfqn_qzgbup.m. Single-class model: L is the per-station demand vector, N the population, Z the think time.

All operations stay in the field, so the bound is exact in rational arithmetic: a bound computed exactly is worth having, since a bound violated only by rounding is indistinguishable from a real violation.
