What happens when more than two edges connect to a single input port?

What happens when more that two edges connect to a single input port? This came up in our weekly meeting and we didn't know the answer.

Also being worked on here: https://github.com/ModECI/MDF/tree/cyclic_graphs

Need to add a field called reduce, can accept one of 2 keywords , add or multiply, and if inputs of different precisions, will return value of highest precision. Any more complex functions required for combining inputs, should be moved to internally in the node with multiple input ports

See: 6b409a0 for initial implementation.

Note: still some open questions about what to do when a single node is run multiple times, e.g. as part of a graph wide condition. Should the current input to the node be added up each time? Probably not, so added a 3rd option overwrite to add and multiply, which is the default for now...
