Names of FinOrdFunctionLazy and FinOrdFunctionMap

[jpfairbanks]

I'm having a hard time remembering these names and I think that the problem is that Lazy and Map aren't semantically related. I think we should use FinOrdFunc and FinOrdVec which are both subtypes of FinOrdFunction or we should use FinOrdLazy and FinOrdEager. Func vs Vec tells you about the storage mechanism and Lazy vs Eager tells you about the evaluation strategy. I'm ok encoding either one, but I think we should be consistent. What do you think?

I agree, the names are long and cumbersome. I'd prefer FinOrdFunc and FinOrdVec.

For consistency, similar changes should be made for the category FinOrdRel, implemented here.
