Calculates the geometric mean. Geometric mean is a type of average which indicates a value in a set of numbers by using the product of values in the set and then taking the nth root, where n is the number of values in the set. This is different than an arithmetic mean, which calculates an average based off the sum of the numbers, and divides it by n number of values. Geometric means can only be positive numbers.
Returns NaN (Not a Number) if passed an empty sequence.
List[Float] values - A sequence of numerical values. Accepts both integers and floats. The sequence may not contain None type values. However, passing a None type object instead of a sequence of numerical values will return NaN.
Float - The geometric mean, or NaN if the input was empty or null. Because this uses logs to compute the geometric mean, will return NaN if any entries are negative.

Code Snippet - Calculating Geometric Mean
# Create a List of values.
values = [3.5, 5.6, 7.8, 7.4, 3.8]
# Prints the resulting value.
