*	Add required mcu specifications	Karel Kočí	2015-03-14
\| \| \| \|	Added mcu specification for previous commits.
*	SPI implemented !NOT TESTED!	Karel Kočí	2015-03-14
\| \| \| \|	SPI for spi hardware implemented, but newer tested yet!
*	SPI USI implementation !NOT TESTED!	Karel Kočí	2015-03-14
\| \| \| \|	SPI on USI implemented. But not tested yet.
*	Add makefile and files.mk	Karel Kočí	2015-03-14
\| \| \| \| \|	Added dummy makefile. Only for cleaning. files.mk is intended for project makefile.
*	Remove documentation	Karel Kočí	2015-03-14
\| \| \| \| \|	Documentation will be hand written. At least until better solution. Problem is with ifdefs.
*	GPIO removed	Karel Kočí	2015-02-08
\| \| \| \| \| \|	Considering limitation of this and high limitations is GPIO removed. Maybe it made code more clear, but direct access to registers is more effective if we want to set multiple pins in one set.
*	Add GPIO input documentation, global config and gitignore	Karel Kočí	2015-02-08
\| \| \| \| \|	Also added gpio_set_not() as simple output negation. Macro definition gpio_set_in is moved up in file to group with gpio_set_out.
*	Initial commit	Karel Kočí	2015-01-29
	Only GPIO output implemented. Implementing: Macros gpio_get_mode(SET, PIN) gpio_set_out(SET, PIN) gpio_set_in(SET, PIN) gpio_set_high(SET, PIN) gpio_set_low(SET, PIN) gpio_set_value(SET, PIN, VALUE)
