// Vampire Numbers

// Our loose definition of Vampire Numbers can be described as follows:

// 6 * 21 = 126
// # 6 and 21 would be valid 'fangs' for a vampire number as the 
// # digits 6, 1, and 2 are present in both the product and multiplicands

// 10 * 11 = 110
// # 110 is not a vampire number since there are three 1's in the
// # multiplicands, but only two 1's in the product

// Create a function that can receive two 'fangs' and determine if the 
// product of the two is a valid vampire number.

// Test.describe("Testing For Vampire Numbers", function(){
//   Test.it("should work for some static tests", function(){
//     Test.assertEquals(vampire_test(21,6), true, "Basic: 21 * 6 = 126 should return true")
//     Test.assertEquals(vampire_test(204,615) , true, "Basic: 204 * 615 = 125460 should return true")
//     Test.assertEquals(vampire_test(30,-51) , true, "One Negative: 30 * -51 = -1530 should return true")
//     Test.assertEquals(vampire_test(-246,-510) , false, "Double Negatives: -246 * -510 = 125460 should return false (The negative signs aren't present on the product)")
//     Test.assertEquals(vampire_test(2947050,8469153) , true, "Large: 2947050 * 8469153 = 24959017348650 should return true")
//     Test.assertEquals(vampire_test(2947051,8469153) , false, "Large: 2947051 * 8469153 = 24959025817803 should return false")
