Was introduced as a work-around to get some debugging info out of scripts, but tests do now provide the same capability with a better output and, do so automatically.
- Update generics syntax
- Add required args to default validator function
This allows running a successful aiken build from
files generated by aiken new.
Pretty useful for debbugging. Though, on second-thoughts, this is
something we may want to review later and maybe have that done by
default for tests.
At the moment, we expects tests to unify to `bool`, and treat `false`
values as failing tests. Yet, on failures, this gives little
information about what's wrong with the test.
It'd be nice to either have better way to assert in tests, or, to
simply accept non-bool tests, and show whatever the test evaluates
to as a debug output.
By default, clap orders command alphabetically, which can be quite
confusing when listing commands with `--help`:
```
SUBCOMMANDS:
eval Evaluate an Untyped Plutus Core program
flat Encode textual Untyped Plutus Core to flat bytes
fmt Format an Untyped Plutus Core program
help Print this message or the help of the given subcommand(s)
unflat Decode flat bytes to textual Untyped Plutus Cor
```
It is possible to instrument clap to order commands in the same way
they are declared in the source, giving us back the freedom to order
and group them in a manner that makes sense, e.g.:
```
SUBCOMMANDS:
fmt Format an Untyped Plutus Core program
eval Evaluate an Untyped Plutus Core program
flat Encode textual Untyped Plutus Core to flat bytes
unflat Decode flat bytes to textual Untyped Plutus Cor
help Print this message or the help of the given subcommand(s)
```
This follows a simple convention:
- `main.rs` contains as little as possible and delegates both
data-types definitions and command executions to sub-modules.
- modules are named after their respective commands. For
sub-commands,
- Each command module can be in one of two forms:
- Either it is a leaf command, and it then contains an `Args`
struct that defines the command arguments; and a function
`exec` when outlines the execution logic.
- Or, it is a group command with multiple sub-commands. In which
case the module defines a `Cmd` struct encapsulating all
sub-commands; and also an `exec` function which simply
dispatches the logic to sub-functions.

This commit also removes the `dev` command which is currently
unused. The rationale being: if it's not there, it's not there.
This was currently in the 'cli' crates, but this code is pretty standalone and need not to be mixed with the rest of the cli logic.
Ideally, we want the cli crate to be only a thin wrapper over functionality available from the rest of the lib crates.
