Function csv_load

tests/memcsv.c:107–182

csv_load assumes the first line in a csv file is a key line, defining entries and their number. First line should not contain 'empty column', i.e. two adjacent commas. Each next line should contain the same number of entries. However, empty columns (two adjacent commas) are allowed. \param rig - a pointer to the rig \param infilename - a string with a file name to wri

     \param infilename - a string with a file name to write to
