 The Storage library for Arduino is designed to abstract handling of
-external memory. It allows block and vector read/write
-(Storage::Block) and streaming of data (Storage::Stream). The library
-includes device drivers for SPI SRAM (MC23LC1024, MC23LC512), 2-Wire
-EEPROM (AT24CXX) and internal EEPROM.
