as \a source argument. In the same way, if a module has an input connector called \c input,
the module may be given directly as \a target argument. This simplifies the most common case
of a module with one input and one output connector.
+
+ The connect call will check at runtime, whether the two connectors are type-compatible:
+ \li Either or both of the connectors are untyped (they accept/send arbitrary senf::Packet's)
+ \li Both connectors send/accept the exactly same packet type.
+
+ \throws connector::IncompatibleConnectorsException if the two connectors are not type
+ compatible.
