'Add a host to this virtual host.
This will take a host named `name\', and map it to a resource
`resrc\'.  For example, a setup for our virtual hosts would be::
nvh.addHost(\'divunal.com\', divunalDirectory)
nvh.addHost(\'www.divunal.com\', divunalDirectory)
nvh.addHost(\'twistedmatrix.com\', twistedMatrixDirectory)
nvh.addHost(\'www.twistedmatrix.com\', twistedMatrixDirectory)'

def addHost(self, name, resrc):

    self.hosts[name] = resrc
