MARKUP_RULESconstant

Default markup rules — the combined block and inline rules MarkupParser uses when none are supplied.

These rules define a syntax similar to Markdown but with improvements:

1. Syntax is more intuitive (e.g. *strong* always uses * asterisk and _em_ always uses _ underscore, and URLs are always autolinked).
2. More compatible with textboxes that wrap lines by default (e.g. single \n linebreaks don't need the trailing double space to, they're always treated as <br />).
3. Don't support fussy fragile syntax that lets users make mistakes (e.g. literal HTML tags or & character entities).
