2f428b7261 split into lib and bin 
* makes most pub things in src/ pub(crate) as not to expose things accidentally
  * only those things needed by src/bin/scryer-prolog.rs and tests/scryer.rs
    should be pub
* split src/main.rs into src/lib.rs and src/bin/scryer-prolog.rs
* add tests folder and run most of the files in src/tests with cargo test
  added bytes method to Stream in src/machine/streams.rs to check if stdout is as expected

099d9aaca6 library(sgml): Correctly parse XML leaf nodes that are not text nodes. 
Example:

    ?- load_xml("<schemaRef type=\"simple\"/>", Node, []).
       Node = [element(schemaRef,[type="simple"],[])].

This is necessary for example to parse XBRL files. See #665.
