chore: Set up development environment

Add the civet and typescript compilers, implement a build step, provide examples of using from es6, script, and command line. Of course, there is no actual behavior produced; convert always produces 'foo' at the moment.

 # vrml1to97

-JavaScript converter from VRML 1.0 to VRML97 file format, based on Wings 3D conversion logic.
+JavaScript converter from VRML 1.0 to VRML97 file format, based on Wings 3D
+conversion logic.
+
+Essentially, this is a JavaScript reimplmentation of the algorithm of the
+"token rearranger" found in the
+[Wings 3D x3d importer](https://github.com/dgud/wings/blob/master/plugins_src/import_export/x3d_import.erl)
+(which was written in Erlang).
+
+## Usage
+
+From an es6 module
+
+```js
+import {convert} from 'vrml1to97'
+const vrml1spec = '# VRML 1.0 ....'
+const vrml97spec = convert(vrml1spec)
+```
+
+or from a script
+
+```js
+(async () => {
+   const vrml1to97 = await import('vrml1to97')
+   const vrml1spec = '# VRML 1.0 ....'
+   const vrml97spec = vrml1to97.convert(vrml1spec)
+})()
+```
+
+or from the command line via node
+
+```shell
+npx vrml1to97 < old.wrl > shinynew.wrl
+```
