Title: Eva node limit, Eva ignores unfruitful rule rewrites

Users can now set a limit to the number of nodes created in an Eva tree. When this limit is reached, Elision will keep processing as normal, but Eva will discard all further TreeBuilder messages until Elision has finished processing its current input.

Also, Eva will no longer create nodes for RewriteRules that don't result in any rewrites.
