##Examples

var chunk = require('node-text-chunk');

var text = chunk.text('HelloWorld!', 5);

console.log('This text is chunked by length and returns an array!\n' + text);

/*
This text is chunked by length and returns an array!
Hello,World,!
*/

var text = chunk.charcode('HelloWorld!', 5);

console.log('This text is chunked by char code length and returns an array!\n' + text);

/*
This text is chunked by char code length and returns an array!
He,ll,oW,or,ld,!
*/

var text = chunk.divide('HelloWorld!', {length: [2, 5], returnUnnamed: false}, function(err){
	console.log(err);
});

console.log('This text is chunked by multiple length parameter and returns an array!\n' + text);

/*
This text is chunked by multiple length parameter and returns an array!
He,lloWo
*/

var text = chunk.divide('HelloWorld!', {length: [2, 5], returnUnnamed: true}, function(err){
	console.log(err);
});

console.log('This text is chunked by multiple length parameter and returns an array!\n' + text);

/*
This text is chunked by multiple length parameter and returns an array!
He,lloWo,rld!
*/

var text = chunk.divide('HelloWorld!', {name: ['one', 'two'], length: [2, 5], returnUnnamed: true}, function(err){
	console.log(err);
});

console.log('This text is chunked by multiple length parameter and returns an object!\n' + JSON.stringify(text));

/*
This text is chunked by multiple length parameter and returns an object!
{"one":"He","two":"lloWo","Unnamed":"rld!"}
*/

var text = chunk.divide('HelloWorld!', {name: ['one', 'escape', 'three'], length: [5, 5, 1], returnUnnamed: true}, function(err){
	console.log(err);
});

console.log('This text is chunked by multiple length parameter and returns an object!\n' + JSON.stringify(text));

/*
This text is chunked by multiple length parameter and returns an object!
{"one":"Hello","three":"!"}
