This is based on the String Calculator kata

This kata is about incremental adding logic to one function.

Write a program that takes a string input and outputs a string
Add to the function StringCalculator, so it can take a string of number (0, 1 or 2 numbers) separated by comma, and return the sum of all numbers
Enable the function StringCalculator to handle an unknown number of arguments.
Enable the function StringCalculator to handle newlines as separators for example "1\n2,3" should return "6".
Don’t allow the input to end in a separator so "1,3," is invalid and should return an error message.
Calling the function StringCalculator with negative numbers will return the message "Negative not allowed : " listing all negative numbers that were in the list of numbers.
Calling the function StringCalculator with multiple errors will return all error messages separated by newlines.

This kata has the expectation that you will incrementally work on the tasks (one step at a time). You have 1 hour to work on this kata.
