### BREAKING CHANGES
* fail is now applied globally.
* we now default to an empty builder function when command is executed with no builder.
* yargs-parser now better handles negative integer values, at the cost of handling numeric option names, e.g., -1 hello
* default: removed undocumented `defaults` alias for `default`.
* introduces a default `help` command which outputs help, as an alternative to a help flag.
