methods

 var concatMap = require('concat-map')

concatMap(xs, fn)

Return an array of concatenated elements by calling fn(x, i) for each element
x and each index i in the array xs.

When fn(x, i) returns an array, its result will be concatenated with the
result array. If fn(x, i) returns anything else, that value will be pushed
onto the end of the result array.
