def read_response(self):
'''
Reads one line from the wire, and interprets it.
Example: the acknowledgment to an unsubscribe
from topic myTopic on the wire looks like this:
*3\r\n$11\r\nUNSUBSCRIBE\r\n$7\r\nmyTopic\r\n:1\r\n'
*3 # three items to follow
$11 # string of 11 chars
UNSUBSCRIBE
$7 # string of 7 chars
myTopic
:1 # one topic subscribed to now
Each line will cause a recursive call to this method
(see elif byte == '*' below).
Simpler calls will be individual elements, such
as ':12', which returns the integer 12.
These are the possible prefixes; each item
is followed by a \r\n, which is stripped
by SocketLineReader:
+<str> simple string
:<int> integer
$<n> string of length <n>
*<num> start of array with <num> elements
When the message to parse is the acknowledgment of
a SUBSCRIBE or UNSUBSCRIBE command, this method
will set() event self.unsubscribeAckEvent/self.unsubscribeAckEvent.
