Functions
int	map_main_header (char *bufr, Main_header *header)
int	mh_update (MatrixFile *)
bool	stir::ecat::ecat7::is_ECAT7_file (const std::string &filename)
	checks if the file is in ECAT7 formatThis partly relies on the implementation of matrix_open in the LLN matrix library. Additional checks are made on the main header. Current checks are:
bool	stir::ecat::ecat7::is_ECAT7_image_file (const std::string &filename)
	checks if the file is in ECAT6 format and if the file contains images
bool	stir::ecat::ecat7::is_ECAT7_emission_file (const std::string &filename)
	checks if the file is in ECAT6 format and if the file contains emission sinograms (or blank/transmision)
bool	stir::ecat::ecat7::is_ECAT7_attenuation_file (const std::string &filename)
	checks if the file is in ECAT6 format and if the file contains attenuation correction factors
Succeeded	stir::ecat::ecat7::read_ECAT7_main_header (Main_header &mhead, const std::string &filename)
	read an ECAT7 main header from a file
void	stir::ecat::ecat7::find_scanner (shared_ptr< Scanner > &scanner_ptr, const Main_header &mhead)
