Added an example of caster construction for type vector (dummy cast, similar to the default one, just for the tuto).

Added boost::ublas::vector example to test_signalcast.

	    * signal-time-dependent.h: new.

	 * contiifstream.h: re-indent and remove trailing white spaces.

     Otherwise, the package does not compile in debug mode.

API to access framework functions without sotInterpreter.
Should ease the port to more complex interpreters without favoring
the internal interpreter. The latter one is here for backward
compatibility. It will be removed.

This version compile but might not work yet.
(not tested).
