Implement blotting for analytics

[CharlesFr]

Implement blotting, create a reports app that has all of the fills, orders, strategy position requests, original API call data (weights), target positions, funding… (ideally everything)

TODO; have a discussion to put some concrete specifications on this

[atkinson]

Yes. Any thoughts on what format this should take?

I guess the best way to answer that is to list out the formulas for the reports we want to generate.

[CharlesFr]

I missed this.

Here's the first commit implementing fills 7a66b37

Did you have in mind to also implement logging of orders? Or do you prefer to keep it simple as it is now (security, exchange & size)
