could it support markdown flow&sequence diagram syntax？

[leion8310]

as like follow syntax
sequence 张三->李四: 嘿，小四儿, 写博客了没? Note right of 李四: 李四愣了一下，说： 李四-->张三: 忙得吐血，哪有时间写。

```flow
st=>start: 开始
e=>end: 结束
op=>operation: 我的操作
cond=>condition: 确认？

st->op->cond
cond(yes)->e
cond(no)->op
```

The syntax highlighting of code fenced blocks is done by the IDE and will support only languages that are defined in the IDE.

If you have a plugin that supports flow syntax installed then it will be supported. The plugin implements the IDE injected language API and the rest is up to the IDE.

@leion8310, if there is a web service that can convert the syntax to an image then you can use the multi-line image url similar to UML diagrams. See #103

@leion8310, I tried to figure out what diagram corresponds to the flow syntax you have given and convert it to start UML syntax.

Is the following diagram close?

The markdown version is:

![graviso](http://g.gravizo.com/g?
@startuml;
(*) --> ["开始"] if "确认？" then;
  -->[结束](*);
else;  
->[no] "我的操作";

For github you will need to copy the generated HTML since it does not handle multi-line gravizo image URLs
