Instead of exporting cantedraw.lib.macro._ and making anyone who wants
to use the --> macro _require_ importing that specific symbol, let's
just make it so the user has to supply a placeholder name before they
do anything. This means each package provides its own placeholder
symbol which lowers coupling.
Splitting macros and functions into different packages and source code
makes it easier to look at. Functions currently implemented:
- range: like Python's range
- parse-integer*: parse-integer but junk-allowed is set to t.
Setup boilerplate for system/package management. In particular, setup
an entry-point and Shinmera's "deploy" to build executables.
Also write some scripts to easily load or build the project without
Emacs - just `sbcl --load <x>.lisp`.
