Add message sequence chart diagrams with mscgen to Trac wiki page

Description

This plugin renders ​mscgen message sequence chart diagrams on a Trac wiki page:

Mscgen is a small program that parses Message Sequence Chart descriptions and produces PNG, SVG, EPS or server side image maps as the output. Message Sequence Charts (MSCs) are a way of representing entities and interactions over some time period. Mscgen is a simplification of Graphviz. It is GPLv2 licensed.

An example of the syntax used:

{{{
#!mscgen
msc {
  hscale = "1";

  a,b,c;

  a->b [ label = "ab()"];
  b->c [ label = "bc(TRUE)"];
  c=>c [ label = "process(1)"];
  c=>c [ label = "process(2)"];
  ...;
  c=>c [ label = "process(n)"];
  c=>c [ label = "process(END)"];
  a<<=c [ label = "callback()"];
  ---  [ label = "If more to run", ID="*" ];
  a->a [ label = "next()"];
  a->c [ label = "ac1()\nac2()"];
  b<-c [ label = "cb(TRUE)"];
  b->b [ label = "stalled(...)"];
  a<-b [ label = "ab() = FALSE"];
}

}}}
