Defines functions computeStats

Documented in computeStats

#' @title computeStats: Calculate count, mean, stdev, and cv of a vector or rows/columns of a matrix, or dataframe
#' @description Returns count, mean, stdev, and cv of vector, matrix or dataframe
#' @param x - vector, matrix or dataframe
#' @param byCol - compute stats by column (if TRUE)
#' @param cols.factors - vector identifying columns to use as factors
#' @param cols.vars - vector identifying columns to use as variables
#' @return 
#' - for x a vector, returns vector with count,mean, stdev and cv as elements \cr
#' - for x a matrix, returns matrix w/ rows with elements count, mean, stdev and cv\cr
#' Rownames correspond to column (or row) names of original matrix.
#' - for x a dataframe, returns NULL (not yet implemented)
