Former - variation of builder pattern.

### Basic use-case

<!-- {{# generate.module_sample{} #}} -->

```rust
use former::Former;
use std::collections::HashMap;

#[derive( Debug, PartialEq, Former )]
pub struct Structure1
{
  int_1 : i32,
  string_1 : String,
  vec_1 : Vec< i32 >,
  hashmap_strings_1 : std::collections::HashMap< String, String >,
  int_optional_1 : core::option::Option< i32 >,
  string_optional_1 : Option< String >,
}
let hashmap = HashMap::from
  ([
    ( "k1".to_string(), "v1".to_string() ),
    ( "k2".to_string(), "v2".to_string() ),
  ]);

let struct1 = Structure1::former()
.int_1( 13 )
.string_1( "Abcd".to_string() )
.vec_1( vec![ 1, 3 ] )
.hashmap_strings_1( hashmap )
.string_optional_1( "dir1" )
.form();
dbg!( &struct1 );

// <  &struct1 = Structure1 {
// <   int_1: 13,
// <   string_1: "Abcd",
// <   vec_1: [
// <       1,
// <       3,
// <   ],
// <   hashmap_strings_1: {
// <       "k1": "v1",
// <       "k2": "v2",
// <   },
// <   int_optional_1: None,
// <   string_optional_1: Some(
// <       "dir1",
