/**
* It took me a whole 6 hours to finally get the color conversion right.
* I have a fairly good understanding of the various color formats (YUV420P, SP, 422, etc etc), 
* and how to access individual Y, U, and V components.
* I however struggled because of a very simple yet hair-pulling gotcha. 
* All primitives in Java are signed! If you come from a Python-like world where 0xFF prints 255, 
* you see yourself struggle just the same. I am however embarrassed at spending 6 hours on this.

Note: I still need to work on the fastai api more to code this without a tabularlist. 
-
I've been doing the fastai course and all the examples put up there are on complicated data - images, text, tables.
I wanted to take a seemingly simple problem of finding the maximum in a list. 
I've only been able to get a 94% accuracy with whatever I've learnt so far. I thought it'd be an accurate 100%,
but maybe I'm just not deep enough into the course yet.

Note, I originally didn't want to classify, but make it a regression problem, but I wasn't able to use the fastai api 
to do so. There's this `FloatList` option, but i can't seem to get it to work.

Keras's ImageDataGenerator is buggy. It first resizes based on `target_size`, 
and then applies the preprocessing function you specified. This sucks.
Who wants that to happen anyway.

Converts Deutsche Bank's CSV of transactions to various categories to see what you're spending money on.

This isn't the neatest code I've written. But it gets what I need done.
I want to see how much I spend on various categories every month. That's it.

Output looks like:
