This module for node.js scans available wifi networks. The main purpose was to enhance my node.js based
[ZigBee Site Survey Tool](http://ancasicolica.github.io/ZigBeeSiteSurvey/) with WiFi coexistence charts. This tool
claims to be compatible with current versions of Mac OS-X, Windows and Linux so I'll fix bugs as fast as possible.

had to handle much more complex network environments and also wanted to be independent of the operating
system language. The adaptions needed would have been too comprehensive for a pull request so I decided to write an own module.
**The module is currently in BETA testing, changes in functionality and interface are possible. Please report bugs on the projects GitHub page, Thanks!**

* airport on Mac OS-X: `airport -s`
* netsh on Windows: `netsh wlan show networks mode=Bssid`
* iwlist (1st choice) on Linux: `iwlist scan`
* nmcli (fallback only) on Linux: `nmcli -m tabular -f SSID,BSSID,SIGNAL,FREQ device wifi`
* iwlist on Linux: `iwlist scan`
Unfortunately, Mac OS-X and Windows use the system language for the output which requires a quite
generic way of parsing the data. If you experience any troubles, please create a GitHub issue and supply
