The tlscommon module is used to perform the actual probe of a TLS server.

It is imported as a submodule of the tlsprober and tlswebprober repos.

The actual protocol actions require a specially instrumented tlslite 
implementation, expanded to support TLS 1.1, TLS 1.2 and several other
TLS features, as well as a large number of special variations of the TLS
protocol, many of them invalid according to the protocol.

The public API is the class probe_server.ProbeServer, which is initiated with a
structure that contain the following elements

	server_item.full_servername = "www.example.com:443:HTTPS"
	server_item.enabled=True
	server_item.alexa_rating=0
	server_item.servername= "www.example.com
	server_item.port= 443
	server_item.protocol = "HTTPS
	server_item.id = 0
  
(In the implementations for which this was originally developed, this
structure was defined as a database record, but that is not necessary)
  
The test is then initiated using code like this:

	import tlscommon.probe_server

	prober = probe_server.ProbeServer(server_item)
	prober.Probe(do_full_test=True)

Results can be presented using field by field check of the "prober" members,
or by printing "prober".
