Series types

[khazaddim]

I have a load candle data function. I also need a function and type for loading econometric data that can just be a line. I may also need another type.

That would make it easuer for people to load data from stuff like FRED.

add a series that is for active positions. it would be higher frequency or event irregular. The time collapse would need to deal with it in a special way. The data in it may be polled from FMP or something.
