Tensor setup via method chaining

[dboyliao]

Sth like this:

Tensor* t = new Tensor();
(t->setShape({3, 3})->setAddress(<address>)->....) // setup whatever you need.

It'll be a lot easier to design a template for the code generator if we have many mechanism to control how tensor behave at the runtime.
Mostly mem allocation for now, but I can see there'll be more to come in the future.

I like the idea of chaining, but what do you mean by setAddress?

[dboyliao]

Oh, It's about @Knight-X's mem allocation optimization pass.
That is, allocate the tensor at specific address (in mem pool managed by uTensor runtime).

aka. offline memory planning

The naming is just for illustrating the idea.
Maybe we can use another more informative name.

Force addressing here is kinda scary, especially if you rope in linker scripts like most people do in production environments

[dboyliao]

Oh, linker scripts.
Well, maybe we need a better naming.
I just want to setup a script how the api would look like though.
Method chaining will make the api and the template much more readable and maintainable.

Method chaining can also be done super efficiently :D
