Changes in version 0.0.1                        

  - New parse_eon() and read_eon() parse eon strings and files into R
    lists. Comments are preserved as eon_comment and eon_suffix_comment
    attributes.

  - New format_eon() and write_eon() serialize R objects to eon strings
    and files. Comment attributes are emitted back into the output, so
    round-trips are lossless.

  - New reformat_eon() normalizes indentation and spacing in an eon
    string without changing data or dropping comments.

  - New validate_eon() returns TRUE or FALSE for whether a string is
    valid eon, without throwing an error.
