javascript code

Problem: How to cope with tons of papers to store?
Solution: Give them systemantic, human-readable filenames.
Syntax: author__title__mag_vol_year.pdf

rules:
* Author is turned to lowercase (easier to find where searching
is case sensitive)
* All non-alphanumeric-characters in the title will be turned
either into '_' or deleted.
* Append the magazine-abbev., the volume and the year - and
celebrate
