EasyCAT Organization

[nicktrem]

• Aimed to make the EasyCATSlave class a little more organized
• There is now an EasyCATSlave base class that can take a specified length, vendor ID, and product code
  • This makes users less likely to make a copy of the EasyCATSlave for their specific project and is thus cleaner from an implementation standpoint
• Added the four default EasyCAT slave configurations provided by the AB&T EasyCAT configure tool
• Updated IHMC EasyCATSlave examples to support the change
