0.1.38
commands.js added pin.cfgs for multiple pin configurations refactored pin.status, pin._state to better handle multiple pins and 08 vs 17 mpc230xx.js changed to not having default sockets but socket can be added by passing lport or lpath now supports new new uci-utils/ready module and adds an observer for when chip and pins are configured mcp230xxi.js now supports new new uci-utils/ready module by adds an observer for when the interrupt process connects and also resets refactored the interrupt methods and commands to compliment changes in the interrupt modulemaster
