This middleware allows register user handlers on commands using patterns like the following:

Request extensions

None

Response extention

None

Example
```
transit = require('transit-im')
app = transit()
app.use transit.commandLine()
app.use transit.commandParser()
app.use transit.autohelp()
```

¶

simple command without arguments

app.receive 'hello', (req, res) ->
  res.sendBack "Hi!"

¶
- command with named arguments. Arguments are space separated. If you need to provide argument with space inside just wrap it in quotes, like this: add2 6 "8 9"
```
app.receive 'add2 {first} {second}', (req, res) ->
  res.sendBack summarize [req.attrs.first, req.attrs.second]
```

¶

command with variable arguments count. there shall be only one variable argument in the pattern

app.receive 'addN {{numbers}}', (req, res) ->
  res.sendBack summarize req.attrs.numbers

app.receive 'stop', (req, res) ->
  res.sendBack ":("
  process.exit()

app.start()

summarize = (numbers) ->
  numbers.map((n)->parseInt(n)).reduce (a,b) -> a + b
