DESCRIPTION
This library allows for easy and simple tcp port checking. 
It can be used for determining if a given port is open, or to find a first available port

INSTALLATION:
npm install portchecker

API:
getFirstAvailable(startPort, endPort, host, cb)
returns first available port in a given range cb(port, host)

getAllOpen(startPort, endPort, host, cb)
returns array of available ports for a given hosts in a given range cb(openPorts, host)

isOpen(port, host, callback)
returns true if a given host:port is open cb(isOpen, port, host)

setTimeout(milisecs)
configure timeout for port probing (default 400 milisecs)


EXAMPLE:

//find first available port between 80 and 90 on localhost
portchecker.getFirstAvailable(80, 90, 'localhost', function(p, host) { console.log(host+":"+p+" is free");});
