CHANGE LOG

2014-02-04: Script now creates supplemental html files for images and numbered tables.
 - added $PUBLISHER variable (must be set to either "bsm" or "fw")
 - added create_supp_file()
 - added calls to create_supp_file() in process_figure() and process_table()

2014-02-14: Fixed bug found by Kevin in process_figure where pattern
for finding $img_file_no_text was too greedy (added '?')

2014-06-02: Added fix_linebreaks() to force browsers to break line correctly
at (em/en)dash

2014-06-02: Added check for inline tags in section titles

2014-06-24: Fixed bug in post_process_section: moved $args =~ s`title="[^"]+"`title=""`; inside of if block

2014-08-15: Added call to fix_linebreaks() in create_supp_file()
