Added a sigmoid xor test and a linear xor test to compare the two. For the sigmoid case to find its solution - it's important for it to have /random/ weights initially, otherwise the output hovers around 0.5 if the weights are initialized to the same value. Updated the linear xor test to match and confirmed it only achieves 25% accuracy, as expected.
