Description

This utility class parses command lines into tokens and allows users to executed based on textual inputs.

In v1, this was possible directly when starting a process, but has been removed based on the security risks associated with this.

By making the shell parsing explicitly, it encourages a user to run a sanity check on the executable before launching it.

Example.

`shell` public construct/copy/destruct

```
() = ;
```

template<typename Char, typename Traits> 
  ( input);

```
(basic_cstring_ref<  input);
```
```
( input);
```
```
() = ;
```
```
( lhs) ;
```
```
 () = ;
```
```
 ( lhs) ;
```
```
~();
```

`shell` public member functions

```
 () ;
```
```
 () ;
```
```
 () ;
```
```
 () ;
```
```
 () ;
```
```
 () ;
```
```
 () ;
```
Native representation of the arguments to be used - excluding the executable.

template<typename Environment = environment::current_view> 
   ( env = ) ;

`shell` private member functions

```
 ();
```
