# MISC
# Intent:
#   This function suppresses the following notes generated by "R CMD check":
#   - "Note: no visible binding for global variable '.->ConfigString'"
#   - "Note: no visible binding for '<<-' assignment to 'ConfigString'"
# Usage:
#   Add the following right in the beginning of the .r file (before the Reference
#   class is defined in the sourced .r file):
#   suppressBindingNotes(c(".->ConfigString","ConfigString"))
.suppressBindingNotes <- function(variablesMentionedInNotes) {
  for(variable in variablesMentionedInNotes) {
    assign(variable,NULL, envir = .GlobalEnv)
