#' Wrapper (*_fit) to call the Time Stratified Petersen Estimator
#' with Diagonal Entries function.
#'
#' Takes the number of marked fish released, the number of recaptures, and the
#' number of unmarked fish and uses Bayesian methods to fit a fit a spline
#' through the population numbers and a hierarchical model for the trap
#' efficiencies over time. The output is written to files and an MCMC object
#' is also created with samples from the posterior.
#'
#' Normally, the wrapper (*_fit) function is called which then calls the
#' fitting routine.

#' Use the \code{\link{TimeStratPetersenNonDiagError_fit}} function for cases
#' where recaptures take place outside the stratum of release.

# Input parameters are
# prefix - prefix used for files created with the analysis results
# this should be in standard Window's format, eg. JC-2002-ST-TSPDE
# to which is appended various suffixes for plots etc
# time - vector of stratum numbers. For example, 9:38 would indicate that the
# Trinity River system sampled weeks 9 to 38. If some values are omitted
# e.g. time=10 not present, this indicates sampling did not take place this
# week. The data are expanded and interpolation for the missing week takes place
# n1, m2, u2 - the input data consisting of fish marked and released, recapture, and unmarked captured
# sampfrac - sampling fraction - depricated because never did work properly
# jump.after - in some cases, a single spline is still not flexible enough to cope with rapid
# changes in the run curve. For example, in the Trinity River project, a larger
# hatchery release occurs around stratum 14. This is a vector indicating the
# strata AFTER which the spline curve is allowed to jump.
# bad.n1 - list of stratum numbers where the value of n1 is suspect.
# Note that if the value of n1 is suspect, the value of m2 is also likely suspect.
# These are replaced by the value of (1,0). We need to specify a value of 1 for bad.n1 values
# because OpenBugs gets upset with n1=0 or n1=NA.
# bad.m2 - list of stratum numbers where the value of m2 is suspect.
# For example, the capture rate could be extremely low.
# These are set to NA prior to the call to OpenBugs
# bad.u2 - list of stratum numbers where the value of u2 is suspect.
# For example, the trap may not be operating completely for some strata, or there was miss counting?
# These are set to NA prior to the call to OpenBugs
# logitP.cov - matrix of covariates for logit(P). If the strata times are "missing" some values, an intercept is assumed
# for the first element of the covariance matrix and 0 for the rest of the covariates.
# CAUTION - this MAY not be what you want to do. It is likely best to enter ALL strata
# if you have any covariates. The default, if not specified, is a constant (the mean logit)
# logitP.fixed, logitP.fixed.values - if you are fixing any of the logit P and at what values.
# tauU.alpha, tauU.beta - parameters for the prior on variance in spline coefficients
# taueU.alpha, taueU.beta - parameters for the prior on variance in log(U) around fitted spline
# prior.beta.logitP.mean, prior.beta.logitP.sd - parameters for the prior on mean logit(P)'s [The intercept term]
# The other covariates are assigned priors of a mean of 0 and a sd of 30
# tauP.alpha, tauP.beta - parameters for the prior on 1/var of residual error in logit(P)'s
# run.prob - percentiles of run timing wanted
# debug - if TRUE, then this is a test run with very small MCMC chains run to test out the data
# and OpenBUGS will run and stop waiting for your to exit and complete
