`path`	path where the .bw files are located.
`regex`	a regular expression (or list of) for selection files in path, default = '.bw'
`junk_list`	a list of substrings to be removed before splitting to levels.
`split_to`	split filenames into levels
`split_by`	delimiter for splitting, default='_'

Creates a data frame with path, filename. Uses the substrings in junk to clean-up the filename and the simplified filename is used with split_to create levels using tidyr::separate function and split_by is the separator used. By default regex is always also removed from filename during simplification.

A tidy data.frame with columns for path filename and all levels.
