v0.2.0

• 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.
