Porting to the attiny85 #11

Hi, i would like to know if its possible to get this library to work with the attiny. Someone tried before, but it doesn't work and they cannot maintain it anymore. I would think it is possible , but the code that takes care of serial communications needs to be replaced as the attiny doesn't have hardware serial.

this are the errors that i get when trying to compile :
