* Print pods from SignedPodBuilder
* Add additional print to test printing SignedPodBuilder
* Mock-prove and print MainPod
* Implement ToFields for custom predicates and dependencies
* Test: print serialization of a recursive batch
* Rearrange serialization of CustomPredicate so args_len is always in the same position
* Serialize predicates with first entry nonzero to avoid collision with padding
* Off by one error in ethdos test BatchSelf(2)
* cargo fmt
* not a typo
* Typos, trying again
* add comments detailing logic, migrate middleware::custom::tests to frontend::custom
* simplify custom predicate's frontend interfaces, making it less verbose to define Statement Template arguments
The main idea is that when defining the arguments at a statement
template, it can be done from 3 different inputs:
i. `(&str, literal)`: this is to set a POD and a field, ie. `(POD, literal("field")`)
ii. `(&str, &str)`: this is to define a origin-key wildcard pair, ie. `(src_origin, src_dest)`
iii. `Value`: this is to define a literal value, ie. `0`
* wip
* prototype custom predicates 1b
* feat: implement custom pred recursion
* files reorg, add github CI for rustfmt checks
* start sparsemerkletree. impl add_leaf method, initial Leaf & Intermediate types with methods
* mt: add hash computation of all the nodes in the tree, add method to print the tree to visualize it as a graphviz
* mt: add (till the leaf) method which is used by get,contains,prove methods
* mt: add verify (of inclusion) method
* mt: update 'down' method to reuse siblings, update get,contains,prove methods (the three use 'down' under the hood)
* Add nonexistence proofs and iterator
* Add iterator test
* migrate usage of old merkletree to the new merkletree impl in POD2 code

* Experiment with statement & op enums
* Clean-up & fixes
* More clean-up
* Add argument length checks
* More clean-up
* Place statement and operation logic in submodules
* Implement Containers (Dictionary,Set,Array) on top of MerkleTree. And restructure the code.
- Reorganize the code grouping backends, middleware, frontend, (crypto) primitives.
- Add types Dictionary,Set,Array at the middleware layer, so that
it can be used both by the backend and frontend. The Dictionary, Set,
Array use the merkletree differently as specified at
f2575d1524/book/src/values.md (dictionary-array-set)
- The containers introduce the trait Container, which has the
method 'cm()'. At the current version this uses a merkletree
under the hood, and the method 'cm' returns the merkle root.
- Ideally neither frontend nor backend use the MerkleTree type, and they
use the wrappers {Dictionary,Set,Array}. Note that the current commit
the MerkleTree is used at the mock-backend to check internal values, but
not at the struct types.
- updated the spec's merkletree section updating the defined interface
- add github ci to run the tests

Migrate fmt to use Display trait to simplify the usage of it.
Also with this, in the same snipped of code we can print types from
backend, middleware and frontend; which before needed to import the two
different `Printer` structs (frontend::Printer and mock_main::Printer).
Before:
```
let printer = mock_main::Printer { skip_none: false };
let mut w = io::stdout();
printer.fmt_mock_main_pod(&mut w, &pod).unwrap();
let printer = frontend::Printer { skip_none: false };
printer.fmt_main_pod_builder(&mut w, &pod_builder).unwrap();
```
now:
```
println!("{:#}", pod);
println!("{:#}", pod_builder);
```
And the equivalent to the old `skip_none: true`, now is done by just
using `println!("{}", pod);
* compute MainPod.id from pub_statements; and introduce the trait `ToFields`
Compute MainPod.id from pub_statements hash; for it, introduce the trait
`ToFields` at the middleware and implement it for the Statement related
types.
* cleaner statements tofield iter
