/**
* \brief Creates a Random Access Sequence for the struct/class named NAME_SEQ
* \param TEMPLATE_PARAMS_SEQ
* \param NAME_SEQ Sequence of a boolean telling if the type is a template type
* or not, followed by the name of the type to be adapted.
*
* That is (0)(mystruct) means adaptation of mystruct a
* non-template type. While (1)(my_tpl_struct) means adaptation
* of a template based struct.
* \param TAG The tag of the Random Access Sequence, this enables to select the
* implementation of the sequence.
* \param IS_VIEW Whether if this creates a sequence of a view from a sequence
* \param ATTRIBUTES_SEQ Sequence of struct attributes to add to the list of
* adapted elements
* \param ATTRIBUTES_CALLBACK Macro callback used to register the attributes into
* the sequence. Usually a call to
* BOOST_FUSION_ADAPT_STRUCT_C_BASE.
