Before, ps would not insert a value if the process didn't have a parent.
Now, ps will insert an empty cell. This caused broken tables as some
rows didn't have all the columns.
* Document the lexer and lightly improve its names
The bulk of this pull request adds a substantial amount of new inline
documentation for the lexer. Along the way, I made a few minor changes
to the names in the lexer, most of which were internal.
The main change that affects other files is renaming `group` to `block`,
since the function is actually parsing a block (a list of groups).
* Further clean up the lexer
- Consolidate the logic of the various token builders into a single type
- Improve and clean up the event-driven BlockParser
- Clean up comment parsing. Comments now contain their original leading
whitespace as well as trailing whitespace, and know how to move some
leading whitespace back into the body based on how the lexer decides
to dedent the comments. This preserves the original whitespace
information while still making it straight-forward to eliminate leading
whitespace in help comments.

* Add possibility to declare optional parameters and switch flags
With this commit applied it is now possible to specify optional parameters and flags
as switches. This PR **only** makes guarantees about **parsing** optional flags and
switches correctly. This PR **does not guarantee flawless functionality** of
optional parameters / switches within scripts.
functionality within scripts. Example:
test.nu
```shell
def my_command [
opt_param?
opt_param2?: int
--switch
] {echo hi nushell}
```
```shell
> source test.nu
> my_command -h
───┬─────────
0 │ hi
1 │ nushell
───┴─────────
Usage:
> my_command <mandatory_param> (opt_param) (opt_param2) {flags}
Parameters:
<mandatory_param>
(opt_param)
(opt_param2)
Flags:
-h, --help: Display this help message
--switch
--opt_flag <any>
```
* Update def docs
* Add rest arg to def
This commit applied adds the ability to define the rest parameter of a def
command. It does not implement the functionality to expand the rest argument in
a user defined def function.
The rest argument has to be exactly worded "...rest".
Example after this PR is applied:
file test.nu
```shell
def my_command [
...rest:int # My rest arg
] {
echo 1 2 3
}
```
```shell
> source test.nu
> my_command -h
Usage:
> my_command ...args {flags}
Parameters:
...args: My rest arg
Flags:
-h, --help: Display this help message
```
* Fix space in help on wrong side
* Remove wrong test case
* Parse long and shortflags without space correctly
* Update param_flag_list.rs
* Update param_flag_list.rs

* move commands, futures.rs, script.rs, utils
* move over maybe_print_errors
* add nu_command crate references to nu_cli
* in commands.rs open up to pub mod from pub(crate)
* nu-cli, nu-command, and nu tests are now passing
* cargo fmt
* clean up nu-cli/src/prelude.rs
* code cleanup
* for some reason lex.rs was not formatted, may be causing my error
* remove mod completion from lib.rs which was not being used along with quickcheck macros
* add in allow unused imports
* comment out one failing external test; comment out one failing internal test
* revert commenting out failing tests; something else might be going on; someone with a windows machine should check and see what is going on with these failing windows tests
* Update Cargo.toml
Extend the optional features to nu-command
