Library Creation

I'm new to C library creation, so I thought I'd work on a simple one to learn. I was able to get an SPI LCD working with a normal project so I then thought to move the initialization and control codes into a library to clean up the main file. Below are my CPP and H files and the references I used to create my code. I suspect my errors stem from the first one and once it's fixed the others will fall out quickly.
