//====================================================================================
//: Read vector from binary stream in an old deprecated format.
// \deprecated in favour of correctly work normal vsl behaviour. Only kept for backwards compatibility.
// If no-one complains about the name change to this code, or otherwise asks for it
// to be kept, then it should be removed after the release of VXL 1.18. The name change will
// however remain, to avoid overriding normal performance of vsl(vec<vec<bool>>) IMS July 2012.
