It is necessary to implement the initial version of the graph and the following classes:

• Variables — mutable objects (tensors) of which we want to know the gradients of

• Constants — immutable objects (tensors) whose value, once specified, does not change

• Placeholders — these are basically empty containers specifying where a future Variable or Constant will go, once we decide what that value should be

• Operators — these are the conceptually hardest to picture, but also the most important

These classes should work with tensors of fixed type (double).
The following mathematical operations and their compositions must be supported:

• addition

• subtraction

• multiplication

• division
