CoreTask#2: BunkerArray - contains the value 1 if and only if it contains a prime number
CoreTask#3: CountDigits - returns the no. of times that a given digit appears in a positive number
CoreTask#4: DualArray - check every value occurs exactly twice or not?
CoreTask#5: DigitSum - returns 1 if sum of all digits of the first argument is less than the second argument and 0 otherwise
CoreTask#6: - Riley - number is an integer whose digits are all even
CoreTask#7: - TwinArray - every prime that has a twin appear with a twin
CoreTask#8: - ConvertToBase10 - <array, base> arguments to a base 10 number
