Helper objects in spiffs_nucleus,h

[jwgod]

I am not quite understanding these two definitions ...

// entries in an **object header page index**
#define SPIFFS_OBJ_HDR_IX_LEN(fs) \
  ((SPIFFS_CFG_LOG_PAGE_SZ(fs) - sizeof(spiffs_page_object_ix_header))/sizeof(spiffs_page_ix))
// entries in an **object page index**
#define SPIFFS_OBJ_IX_LEN(fs) \
  ((SPIFFS_CFG_LOG_PAGE_SZ(fs) - sizeof(spiffs_page_object_ix))/sizeof(spiffs_page_ix))

particularly object header page index and object page index. What are those?

Thanks
