* move commands, futures.rs, script.rs, utils * move over maybe_print_errors * add nu_command crate references to nu_cli * in commands.rs open up to pub mod from pub(crate) * nu-cli, nu-command, and nu tests are now passing * cargo fmt * clean up nu-cli/src/prelude.rs * code cleanup * for some reason lex.rs was not formatted, may be causing my error * remove mod completion from lib.rs which was not being used along with quickcheck macros * add in allow unused imports * comment out one failing external test; comment out one failing internal test * revert commenting out failing tests; something else might be going on; someone with a windows machine should check and see what is going on with these failing windows tests * Update Cargo.toml Extend the optional features to nu-command Co-authored-by: Jonathan Turner <jonathandturner@users.noreply.github.com>
