Python 3 support

[chadgh]

It would be great to have python 3 supported. If it isn't a high priority for you and you don't know of any major issues with porting it to support python 3, I wouldn't mind helping with that.

please do. thank you. make changes to the tex, not the nlib, since the latter is auto-generated from the book.

This issue was opened more than a year ago. Can I take this up? @mdipierro

[chadgh]

@avinassh Go for it. I unfortunately haven't done anything with this yet. Sorry.

[mdipierro]

yes. Thank you!

[avinassh]

Great. I will get started asap.

Any instructions on building the tex file? and also, the whole book is in a single tex file, wouldn't it be better to split it chapter wise?

[mdipierro]

I have code that takes the book and spits out and tests the nlib.py. I would rather keep it as it is. :-)

[avinassh]

Sure. No problem!

Can you give me instructions on building the book and also testing the code? I already MacTex installed and running.

[mdipierro]

building the book is just "pdflatex book_numerical.tex". I usually run it 3 times to make sure citations show up correctly. I will commit the code for the testing
