* Added Julia, Rust, and R support.
* Added boolean keyword argument `complete` for code chunks. This allows code
chunks that contain incomplete units of code, such as part of a function
definition or part of a loop. Any stdout from a chunk with `complete=false`
will appear with the next chunk with `complete=true` (the default value).
* Session hashes are now more robust by including session names and chunk
`complete` status. This prevents the collision of sessions with identical
code but different processing for code output.
* Added boolean keyword argument `example` for code chunks. This displays the
Markdown source along with the output, putting both inside a single div with
class `example` and putting them individually in divs with classes
`exampleMarkup` and `exampleOutput`, respectively.
* Added boolean keyword argument `outside_main` for code chunks. Code chunks
with `outside_main=true` at the beginning of a session will overwrite the
beginning of the Codebraid source template, while code chunks with
`outside_main=true` at the end of a session will overwrite the end of the
source template. This is primarily for compiled languages like Rust, so
that the implicit `main()` function defined in the default source template
can be overwritten.
* In language definitions, `source_start` and `source_end` are now combined
into a single `source_template`. Delimiter fields are renamed to
`stdout_delim` and `stderr_delim` (added underscore to parallel future,
optional delimiters).
* There is no longer any attempt to sync `RawInline` HTML precisely with the
document source, since this can fail in some cases with HTML comments.
`RawBlock` HTML was already not synced precisely due to similar issues.
* More robust stdout and stderr parsing.
