TMD: a new markup language which is more specified and powerful than tranditional markdown

Hi, this is my first zig project. I’m a tech book/article writer and often found that markdown is too limited but the readability of some other alternatives with more features is not good. So I decided to create new format about one year and half ago.

That means the format has been designed for one year and half. Many design iterations happened during the period. It is still far to perfect. But there has to be a start. So I decided to release it now. Would love some feedback on this!
