Function 'function' field is dict instead of str

[kmantel]

Since d1f4937, the 'function' field of Function is a dict (changed from str) expected to contain args and their values. ex:

MDF/examples/MDF/translation/Translated_ABCD.json

Lines 122 to 130 in 48e2b2e

	"function": {
	"exponential": {
	"variable0": "input_port1",
	"scale": "scale",
	"rate": "rate",
	"bias": "bias",
	"offset": "offset"
	}
	}

Why use this dictionary format instead of handling the function arguments in the 'args' field as with evaluable expressions? This change seems to add extra complexity

This issue is more to track a proposed design change to the MDF formal specification for parameters and functions rather than a bug fix I'm afraid. It requires examination of the merits of the change by the MDF developers rather than something that just needs a quick change in the code, so is probably something more for the actual internship rather than the contribution phase.
