broken but closer, base graph builds in slightly incorrect format causing later issues in crawl
code working together somewhat
binarytree.c insert fixed
Move url-cleaning from parser to crawler_control. Add string_llist_free and string_llist_empty. Use one call to parse_all instead of two.
remove unneeded debugging output
add auth and hub score to struct urlinfo.h
ranksort.c quicksorts an array of urlinfo pointers via their auth score
add makefile for test on ranksort, run with "makefile -f sorttest.mk"
add comments and modify utils/ranksort.h to make functions hidden
add ranksorttest to .gitignore
