`folder`	the path to the folder containing the files to be merged. The files must be in csv format.
`filename_pattern`	a search term to find files that should be merged (inside the folder). You can use R style 'regex' patterns if you set use_regex=T
`output_file`	full path to the file the merged dataset should be written to. If NULL (default), no output file is written.
`write_log`	if TRUE, writes an html file with a log of the merge and subsequent checks.
`use_regex`	if TRUE, searches the 'folder' directory for 'filename_pattern' using regex patterns. Defaults to FALSE.
`add_file_reference`	If TRUE (default), adds a new column called 'MERGED_FROM_FILE' containing the file name of each records source file.
`verbose`	if TRUE writes messages to console during merge; set to FALSE to make quiet.
