SumArrays.java

//8th kyu
//Write a method that takes an array of numbers and returns the sum of the numbers. 
//The numbers can be negative or non-integer. 
//If the array does not contain any numbers then you should return 0.
//Assumptions: You can assume that you are only given numbers.
//You cannot assume the size of the array.
//You can assume that you do get an array and if the array is empty, return 0.
//Example: [1, 5.2, 4, 0, -1] => 9.2
