Methods for formatted recording of color output.

# Easy methods of formatted recording

```
#[macro_use]
extern crate clucolor;

let str_colored = color!(blue, "test");
println!("{}", str_colored);
	
let str_colored = color!(blue, bold, "test");
println!("{}", str_colored);

	
let str_colored = color!(bright_red, bold, "test");
println!("{}", str_colored);
```

# Generating a string using color types

```
#[macro_use]
extern crate clucolor;

use clucolor::colors::cluColor;
use clucolor::colors::BrightRed;

let string = BrightRed::string_fmt( format_args!("[{:?}] {}", TEST, str) );
let string = BrightRed::stringn( "color str!" );

```


# Recording macros in `Write trait`

```
#[macro_use]
extern crate clucolor;

use clucolor::colors::Blue;
use clucolor::colors::BrightBlue;


writen_color!(&mut ::std::io::stdout(), BrightBlue, "OutValueTest {}", 123);
writen_color!(&mut ::std::io::stdout(), BrightBlue, "OutValueTest2 {}", 12345);
writen_color!(&mut File::open("color_file.txt"), BrightBlue, "Color Str:)", 12345);
```

# Recording using color types

```
#[macro_use]
extern crate clucolor;

use clucolor::colors::Blue;
use clucolor::colors::BrightBlue;


let mut vec: Vec<u8> = Vec::new(); // For Vec implemented Write!!


let _e = BrightBlue::write_str(&mut vec, "color str!" );

let _e = vec.write(b"TestValue"); // For Vec implemented Write!!
//Also this value will remain without color formatting.

let _e = BrightBlue::writen_str(&mut vec, "end str.." );

let _e = BrightRed::writen(&mut vec, b"end value.." );

```

# Use move color arguments
```
#[macro_use]
extern crate clucolor;

use clucolor::colors::BrightBlue;

#[derive(Debug, Default)]
pub struct Items(usize, usize);

impl Items {
     #[inline]
     pub fn count(&self) -> usize {
          self.0 + self.1
     }
}

let mut item = Items::default();

for a in 0..15 {
     BrightGreen::with_color_fmt(format_args!("NUM #{}", a), |fmt_num| {
          BrightBlue::with_color_fmt(format_args!("ITEM #{:?}", item), |fmt_item| {
               BrightRed::with_color_fmt(format_args!("ALL_COUNT {}", item.count()), |fmt_count| {
                    println!("{}, {}; {};", fmt_num, fmt_item, fmt_count);
               });
          });
     });

     item.0 += 1;
     item.1 += 2;
}

```


# Use ColorWriter
```
#[macro_use]
extern crate clucolor;

use clucolor::colors::Blue;

let writer = Blue::writer();
	
let stdout = ::std::io::stdout();
let mut lock_stdio = stdout.lock();
	
writer.writen(&mut lock_stdio, b"TestWriten").unwrap();
```

All other functions are implemented in color mod with the help of cluColor!
