Merge Transformed Parameters and Model Blocks

#### Summary: The point of this feature request is to merge the `transformed parameters` and `model` blocks, as the added complexity of having them be separate entities seems unnecessary. ####...

Start collecting open interest data?

An idea for a potential new feature: collecting open interest data. IB provides it, so it shouldn't be hard at all. Example code: ``` from ib_insync import * util.startLoop() ib...

It would be useful to add support for statically evaluating functions like `size`, `dims`, `num_elements`, `max`, `min`, `rows`, `cols` when called on array, vector and row-vector expressions like `{4, 2,...

I believe Read_Param__ and Write_Param__ are the necessary ones.

The idea is to automatically determine when variables can go out of scope because they are no longer needed. (Relying on a live variables analysis.) There is another question here:...

For example, to automate things like this: ``` for (n in 1:240) y[n] ~ normal(mu, sigma); ``` becomes ``` y[1:240] ~ normal(mu, sigma); ```

The issue is to check correctness of the optimization in the issue title and to wire it up in the Stan_math backend (after the backend specific transformations). For now, it...
