tests/cpydiff: Add initial set of tests for uPy-CPython differences. These tests are intended to fail, as they provide a programatic record of differences between uPy and CPython. They also contain a special comment at the start of the file which has meta-data describing the difference, including known causes and known workarounds. 2017-02-07 04:55:37 +00:00			`"""`
