BEM class name formatter

## Example

### Simple

```js

var b = require('b_');

// blocks

b('button', {size: 'xl'}) === 'button button_size_xl';

// block elements

b('modal', 'close', {size: 'xl'}) === 'modal__close modal__close_size_xl';

// boolean modifiers

b('button', {hidden: false}) === 'button';

b('button', {hidden: true}) === 'button button_hidden';

```

### Alternative BEM syntax

```js

var B = require('b_').B;

var b = B({

    tailSpace: ' ',

    elementSeparator: '-',

    modSeparator: '--',

    modValueSeparator: '-',

    classSeparator: ' '

});

b('block', 'elem', {mod1: true, mod2: false, mod3: 'mod3'}) ===

'block-elem block-elem--mod1 block-elem--mod3-mod3 ';

```

### [BEViS](https://github.com/bevis-ui/docs) syntax

```js

var B = require('b_').B;

var b = B({isFullModifier: false});

b('button_call-for-action', {disabled: true, focused: 'yes'}) ===

'button_call-for-action _disabled _focused_yes';

```

### Full bool values in modifiers

```js

var B = require('b_').B;

var b = B({isFullBoolValue: true});

b('button', {disabled: true, focused: false}) ===

'button button_disabled_true button_focused_false';

```

### React example

```jsx

var b = require('b_').with('b-button');

// or

var b = require('b_').lock('b-button');

// which is `require('b_').bind(null, 'b-button');` but much convenient

function render() {

    return (

        


            

            

        

        


            

            

        

    );

}

```
