#' The CaSpER Class
#' The casper object is required for performing CNV analysis on single-cell and bulk RNA-Seq. It stores all information
#' associated with the dataset, including data, smoothed data, baf values, annotations, scale specific segments, scale specific large scale events etc.
#'
#' @slot raw.data raw project data
#'
#' @slot data lowly expressed genes are filtered from the data
#'
#' @slot loh original baf signal
#'
#' @slot filtered.data median filtered expression signal
#'
#' @slot loh.median.filtered.data median filtered baf signal
#'
#' @slot centered.data gene expression levels are centered around the mid-point. For each gene, the mid-point of expression level is computed among all the cells (or samples in bulk RNA-seq), then the mid-point expression level is subtracted from the expression levels
#'
#' @slot center.smoothed.data cell centric expression centering is performed. For each cell (or sample), we compute the mid-point of the expression level then we subtract the mid-point expression from the expression levels of all the genes for the corresponding cel
#'
#' @slot control.normalized control normalization is performed by subtracting reference expression values from the tumor expression values.
#'
#' @slot control.normalized.noiseRemoved noise is removed from control normalized and thresholded data.
#'
#' @slot large.scale.cnv.events large scale CNV events identified by CaSpER
#'
#' @slot segments CNV segments identified by CaSpER
#'
#' @slot cytoband cytoband information downloaded from UCSC hg19: http://hgdownload.cse.ucsc.edu/goldenpath/hg19/database/cytoBand.txt.gz hg38:http://hgdownload.cse.ucsc.edu/goldenpath/hg38/database/cytoBand.txt.gz
#'
#' @slot annotation positions of each gene along each chromosome in the genome
#'
#' @slot annotation.filt lowly expressed genes are filtered from gene annotation data.frame
#'
#' @slot control.sample.ids vector containing the reference (normal) cell (sample) names
#'

#' @slot hmmparam initial hmm parameters estimated from data
#'
#' @slot plotorder cell (sample) ordering for heatmap plots
#'
#' @slot vis.bound threshold for control normalized data for better visualization
#'
#' @slot noise.thr noise threshold for better visualization
#'
#' @slot loh.name.mapping containing the cell (sample) name and the matching baf signal sample name
#'
#' @slot sequencing.type sequencing type: bulk or single-cell
#'
#' @slot cnv.scale maximum expression scale
#'
#' @slot loh.scale maximum baf scale
#'
#' @slot loh.shift.thr baf shift threshold estimated from baf signal using gaussian mixture models
