This function will take a [1xn] or [mx1] vector and normalize it to a unit vector length.

To use this function [vectorOut] = fcn_createUnitVector(vectorIn)

Error checking is performed to test for NaN values in the output, and a square root of the sum of the squares == 1

This function will take column or row vectors and output in said format.
