41 *\brief Defines Data and DataInfo
43 * Data is bbtk general type exchanged between black boxes (adapted from boost::any).
44 * DataInfo is the bbtk type of object storing informations on a data type : includes C++ type info (std::type_info) and a string describing the "nature" of the data (what is the content of the structure).
