* Move lite_parse tests into a submodule * Have lite_parse return partial parses when error encountered. Although a parse fails, we can generally still return what was successfully parsed. This is useful, for example, when figuring out completions at some cursor position, because we can map the cursor to something more structured (e.g., cursor is at a flag name).
