This type was a special case of a custom implemented list, and was used
like a map. I have replaced it with a std::map typedef'd as
ScaFuncDataMap.

Since the map key also exists in the value object, there are more
memory-efficient ways to implement this with a vector and a predicate
functor for searching at the cost of some code complexity. I opted for
the simpler code afforded by using a std::map implementation.
