In databio/RPIM: Assess epigenetic heterogeneity with proportion of intermediate methylation

#' Assess epigenetic heterogeneity with proportion of intermediate methylation
#'
#' Provides a score called PIM that measures the epigenetic heterogeneity in a
#'     bisulfite sequencing sample. Under the assumption that a homogeneous
#'     sample will have mostly CpGs with either 100% or 0% DNA methylation, it
#'     follows that the proportion of sites that differ from these two extremes
#'     can be used as a measure of sample heterogeneity.
