l.s.w.v.VirtualHostConfig : class documentation

Return list of hostname strings given a string of althostnames.

This is to parse althostnames from the launchpad.conf file.

Basically, it's a comma separated list, but we're quite flexible about what is accepted. See the examples in the following doctest.

>>> thismethod = VirtualHostConfig._hostnameStrToList
>>> thismethod('foo')
['foo']
>>> thismethod('foo,bar, baz')
['foo', 'bar', 'baz']
>>> thismethod('foo,,bar, ,baz ,')
['foo', 'bar', 'baz']
>>> thismethod('')
[]
>>> thismethod(' ')
[]
