for replace script run: `make replace`

Specific Dependencies:
* NLTK English Corpus:

* PDF generation for Python (FPDF): `pip3 install fpdf`
* HTML5lib: `pip3 install html5lib`

Notes & Bugs:
This script is very picky about the input images it can work with. For best results, please use high resolution images in RGB colorspace. Errors can occur when image modes do not match or tesseract cannot successfully make HOCR files.
