now with getDataForPins method
remove console log, add variable explaning the significance of 10
wrapped JSON.parse in a try catch for the cache so that instead of crashing when file did not cache properly we just act like there is no cache
Refactored code a bit so that getDataForPins was a static method
added arbitrary limit of 50 to the parallel calls made to pinterest, just in case people go buckwild
