Dense Layer, Add

added the dense layer with a forward functions. I also made the add functions for most cases.

 // Description:
-//   A dense layer to use in neural networks
+//   A base layer to use in neural networks
 //
 // Member Variables:
-//   length       panic::uint_t
-//                Number of elements in the vector.
-//
-//   data         panic::real_t*
-//                Pointer to the allocated vector data.
+//   None.	      
 //
 // Notes:
-//   This vector uses dynamic allocation with new[] and delete[].
-//   Copying performs a deep copy.
+//   	This base layer should be used in all layers/activations that have a forward and backward function
+//		This is done so it's easy to make a list of layers in the model to loop over.
+//		The virtual means it should use derived object's version when called with a pointer.
+//		The =0 means the derviced object NEEDS to have these functions to work.
