Added Okasaki's Random Access List to standard library
edge case when needle is "" would cause runtime errors...whups
Change makefile to pass through exit code for Travis
compile tests for edge cases of string-containment
Moved RAList out of library into examples
missing calls to mk-str in runtime, and new tests to catch them in the future
Added more higher-order functions on RAList
Type for NodeTree now disallows empty trees, as that would be an invariant violation
Removing check for size-1 nt-branch in rrest
improving error reporting from within get-raw-field, such that errors
in custom _torepr methods don't trigger infinite looping (an error
causes _torepr to be called, which causes an error, the reporting of
which in turn calls _torepr again...)
minor UI fix
Adding extra functions and methods to make RAList API match List API
