## Description: function Report_Number_Generation
## This function creates a reference for the submitted
## document and saves it in the specified file.
## Author: T.Baron
##
## PARAMETERS: edsrn: name of the file in which the reference is saved
## autorngen: one of "A", "N", "Y"
## "A": The reference is the submission number
## "N": The reference is taken from a file [edsrn]
## "Y": The reference is generated
## rnin: name of the file containing the category
## counterpath: path to the counter file
## rnformat: format for the generated reference
## yeargen: if "AUTO", current year, else the year is
## extracted from the file [yeargen]
