Composite.calcTotalParam needs some TLC

[john-science]

I believe this method has gotten kind of stale, and needs some love:

Some issues:

1. It only works if you call it on an Assembly or a Core, but it is defined on the generic Composite.
2. This method is used in a lot of places downstream, but I believe a few of the input parameters are never used by anyone. We should clean those out.
3. This method needs to... at least, have a warning in the docstring that notes that not all params CAN be summed meaningfully.
   • This method is kind of risky. Not all parameters can be meaningfully summed. And the user has to KNOW.
4. The code itself also needs a little TLC, this naming convention is pretty whiffy:
