+## Example
+
+```
+let spawnGenerator = require('spawn-generator');
+
+let generatorFunction = function*(fruit) {
+  let fruits = [];
+  fruits.push(yield asyncMethod('apple')); // asyncMethod returns Promise
+  fruits.push(yield asyncMethod(fruit));
+  return fruits;
+};
+
+let functionToCall = spawnGenerator(generatorFunction);
+functionToCall('banana')
+  .then(
+    (fruits) => console.log(fruits) // outputs ['apple', 'banana']
+  );
+
+spawnGenerator(generatorFunction, 'orange')
+  .then(
+    (fruits) => console.log(fruits) // outputs ['apple', 'orange']
+  );
