Introduction
============

Fast radio bursts (FRBs) are a relatively new class of radio transient that are short, bright and highly dispersed. The pulses are typically of durations of a few milliseconds, and exhibit dispersion sweeps characteristic of propagation through a cold diffuse plasma [@Lorimer; @Thornton]. The dispersion measures (DMs) of these pulses are significantly higher than the contribution from the line-of-sight through the Galactic Interstellar Medium (ISM), suggestive of a cosmological origin in which the large DMs are due to passage through the Intergalactic Medium (IGM). If they are at cosmological distances, their inferred intrinsic energies ($>
