Documentor

[skygering]

We have a lot of warnings from Documenter.jl when generating the documentation. I fixed some of them in #50, but not all of them.

1. Warning: failed to run @example block in src/source/methods/barycentric.md:28-102
   This looks like a Makie issue - will take a look.
2. Looks like a lot of SVG/vector images are being made to convert to PNG because of a Documenter file size limit (I guess this is relatively recent?)

    Warning: Generated HTML over size_threshold_warn limit: index.md
    Generated file size: 106.91 (KiB)
    size_threshold_warn: 100.0 (KiB)
    size_threshold:      200.0 (KiB)
    HTML file:           index.html
Warning: For 18 @example blocks, the 'text/html' representation of the resulting
object is above the the threshold (example_size_threshold: 8192 bytes).
- 18 blocks had 'image/png' fallback image representation available, using that.

should be mostly fixed now
