Fake sampler for likelihood consistency check
Implement a "fake sampler" which reads in a set of parameters from a file, and then computes the likelihood for those paramters. This would be a really useful consistency check between the ROQ and nonROQ likelihood functions, as well as an useful check for when the likelihood function is updated/appended (as, in order to accept a merge request to the likelihood function it needs to sufficiently reproduce the likelihood values from a fiducial set of parameter samples)
