In masscor: Mass Measurement Corrections

#' \code{masscor}: Mass Measurement Corrections and Uncertainties.
#'
#' The \code{R} package \code{masscor} provides functions, classes and methods
#' to support mass measurements using non automatic balances as described in
#' EURAMET's Calibration Guide No. 18 (2015).
#' The new classes are objects that can store the calibration information for
#' balances and mass standards. Those objects can be used to convert balance readings to
#' both conventional mass and mass, and to perform routine balance verification
#' (by using the normalized error function).
#' Air buoyancy correction factors are calculated using local air density that
#' can be calculated using environmental conditions and applying one
#' of several models available in the package. The uncertainty of (corrected)
#' mass measurements can also be evaluated allowing us to further assess the suitability
#' of given mass measurement.
#'
#' @section \code{masscor} functions:
#' This package uses list objects of class \code{'calibCert'} to store information
#' of balance calibration certificates.
#' The functions use the information of this object to convert balance reading
#' indications to conventional mass and calculate mass
#' uncertainties.
#'
#' Several models for calculating air density are included and this
#' information can be used to calculate the
#' Magnitude of the Air Buoyancy Correction factor (MABC).
#' Uncertainties calculations are made using Gauss Approximation according to the
#' Guide to the Expression of Uncertainty in Measurement (GUM) implemented in
#' \code{R} by the package
#' \link[metRology]{metRology} (Ellison, 2018).
