Updating some comments and starting to make the library.

I am starting with a static library and then have some scripts to pull together a header only maybe.

Currently working on getting the base library interface figured out through some TDD. I am mirroring libxml interface and using that as a guide.

-# C++ DBC Header Only File Parser
+# C++ DBC Parser
 
 This is to provide a library header only file to read in DBC files. I was looking around and couldn't
 find a simple library that didn't have dependencies. So here we are making one. I got some inspiration
