stricter similar-atoms function
make get-mapping uses similar-atoms
allowed unordered-link, enforce structural match on all nodes/links
changed similar-1-to-n to similar-n-to-nm to fix a bug
instead of selecting first mapping, check all mapping to see which one has name matches
work around for matching node, where returned result is not list of lists
added new version of cartesian-product that works better with lists
fixes problem of not combining results correctly
added missing documentation formatting
fixed buggy commit
fixes incorrect handling of #f
