Estimate pose between two laser scans

`pose = matchScans(currScan,refScan)`

`pose = matchScans(currRanges,currAngles,refRanges,refAngles)`

```
[pose,stats]
= matchScans(___)
```

`[___] = matchScans(___,Name,Value)`

finds the relative pose between two laser scans specified as ranges and
angles.`pose`

= matchScans(`currRanges`

,`currAngles`

,`refRanges`

,`refAngles`

)

`[___] = matchScans(___,Name,Value)`

specifies additional options specified by one or more
`Name,Value`

pair arguments.
