 - implement convolutional layers and perhaps even solve some image classification problems in a example
 - have some feature of Intricate, should be optional, that would contain preloaded datasets, such as MNIST and others
 - write many more unit tests to make code safer, like a test for the backprop of every activation layer
-- perhaps write some kind of utility functions to help with writing repetitive tests for the backprop of activation functions
-- improve documentation of Intricate overall, like adding at least a general description for every mod
