#' @description Function to render a document of comparison plots for model fits to
#' size composition data by year.
#'
#' @param models - named list of model results (as resLst objects) to compare
#' @param plot1stObs - flag to plot observed data only from first model
#' @param output_format - "word_document" or "pdf_document"
#' @param output_dir - path to folder to use for output
#' @param rmd_dir - folder enclosing rmd file
#' @param rmd - Rmd file to process (defalut="modelComparisons.Rmd")
#' @param docx_styles - full path to Word (docx) style template for Word documents
#' @param pdf_styles - full path to style template for pdf documents
#' @param clean - T/F to delete intermediate files
#'
#' @details Resulting document title will be of the form "ModelComparisons.ModelFits.ZCsByYear.mmm.ext",
#' where "ext" is the appropriate file extension and "mmm" is a dash-separated string of model names.
