Defines functions CheckInput

Documented in CheckInput

#' Main Check Input function
#'
#' This function perform multiple tasks. First of all, check the parameters specified by the user.  Also asign default values to some parameters not defined by the user. Finally it generates error  messages and halt the execution in case it is needed.
#' @param datatable Matrix. Expected to be square matrix with at least 2 rows (columns), non negative values and at least an element different of zero.
#' @param fixedrows Boolean. Indicate if sample rows are fixed beforehand. Default is TRUE.
#' @param gstandard Text. Indicate if there are a Gold Standard by Rows or columns. Only first letter matter without Case sensitivity. Options are: "N" for None, "R" for in Rows and "C" for in Columns. Default is "N".
#' @param maxits Whole number. Indicate the maximum number of iterations of the numeric method to calculate B. Expected to be 100 <= maxits <= 5000. Default is 1000.
#' @param tol Double number. Indicate the precision of the numeric method to calculate B. Expected to be 1e-6 <= tol <= 1e-15.Default is 1e-12.
#' @param dplaces Whole number. Decimal placed to be shown in the result. Expected to be 1 <= dplaces <0 6. Default 4.
#' @param showall Boolean. Indicate if all output should be shown. If TRUE also shown hidden results. If FALSE shown only main output. By default is FALSE.
