Example usage
-------------
First install the component

    npm install --save react-click-n-hold

Then use the component in your app

    import React from 'react';
    import ClickNHold from 'react-click-n-hold'; 
    
    export default class Example extends React.Component {
    	start(e){
    		console.log('START'); 
    	} 
        
    	end(e, enough){
    		console.log('END');
            console.log(enough ? 'Click released after enough time': 'Click released too soon');            
    	} 
        
    	clickNHold(e){
    		console.log('CLICK AND HOLD');  
    	} 

    	render(){
    		return ( 
    			<ClickNHold 
    				time={2} // Time to keep pressing. Default is 2
    				onStart={this.start} // Start callback
    				onClickNHold={this.clickNHold} //Timeout callback
    				onEnd={this.end} > // Click release callback
    					<button>Click and hold</button>
    			</ClickNHold>
    		); 
    	}
    }

> **Styling animation:**
> - This component does not provide css for pressing effects
> - However, during press, .cnh_holding is applied to the wrapper, allowing the user to animate the transition using css
> - Below is an example of styling; the one used in the demo
 
   
      
    @-webkit-keyframes fill { 
      to {
       background-size: 100% 0; 
      }
    } 
    
    @keyframes fill { 
      to { 
       background-size: 100% 0;
      }
    }
    
    //The wrapper has the .cnh_holding class while the button is being pressed
    
    .cnh_holding button {
      background: -webkit-linear-gradient( white , white) rgb(255,215,235) no-repeat 0 0;
      background: linear-gradient( white , white) rgb(255,215,235) no-repeat 0 0;
      mix-blend-mode: multiply;
      background-size: 100% 100%;
      -webkit-animation: fill 2s forwards;
      animation: fill 2s forwards;
    }
