feat: Flat import of markdown repo

This is a flat (without history) import of (some of) the content
from our markdown module.

We've imported this without history because the repo contains our
blog posts and showcases posts content prior to porting them to strapi.

Since this contains many images, it would balloon the size of this repo
to import the full history.

Instead, please refer to the history of the (archived) markdown repo
at: https://github.com/freesewing/markdown

+
+```js
+Pattern pattern.sampleMeasurement(string measurement)
+``` 
+
+Samples a measurement by drafting 10 variations of the pattern 
+while adapting the measurement between 90% and 110% of its original value.
+
+The goal of measurement sampling is to understand the impact of a given measurement on a pattern.
+
+```js
+import freesewing from "@freesewing/core"
+import aaron from "@freesewing/aaron"
+import models from "@freesewing/models"
+
+let pattern = new aaron({
+  settings: {
+    embed: true,
+    measurements: models.manSize38
+  }, 
+})
+
+let svg = pattern.sampleMeasurement("chestCircumference").render()
+```
