  { name: 'ziva', age: 2 },

]

const piles = pileSort(records, [
  (record) => record.age < 13,     // isChild
  (record) => record.age < 20      // isTeen
])
// [
//   [
//     { name: 'ziva', age: 2 }    // isChild
//   ],
//   [
//     { name: 'lev', age: 13 }    // isTeen
//   ],
//   [
//     { name: 'alice', age: 34 }, // remainder

//   ]
// ]

const [ children, teens, remainder ] = piles

API

pileSort(records, filters) => results

where:

• records is an Array of items you want to seperate
• filters is an Array of n filters which will be used to sort into piles. These are applied in order till a match is found (returns true). If no match is found, the item will default to a "remainder" pile
• results is an Array of n + 1 Arrays
  • n piles for each of the filters,
  • 1 pile on the end "remainder" (items which didn't match any of the filters)
