New Library: SDCore: read and write blocks to SD Cards

Hi,

I'm new to the forum and this is my first library to Arduino boards.

Its an extreme lightweight library to read and write blocks to SD and SDHD cards using any SD Card board and the SPI interface.

It should work with most AVR boards, but i only have a Uno to test it.

I wrote a readme with all documentations about how to use and the library has some examples:

I need help testing, specially in other boards than UNO and I need alot of feedback if possible.

Sorry for my bad english and thank you all in advance.
