#' plot grouped CSMF from a "insilico" object

Significant sections of this code undergo hard-to-read loop-based processing and plotting that is nonintuitive to ggplot. For example, all of the if/else plotting statements at the end could be simplified - maybe not in number of lines but at least in terms of organization and readability - to more modular chunks of ggplot layers relying on dplyr-based transformations of the dataset. Making such a change would increase the readability of the code, make it easier to maintain, and also likely simplify and optimize processing.
