Changes

===Google Scholar Crawler===

I used the selenium box and switched from Rice Visitor, Rice Owls, and eduroam to prevent Google Scholar from blocking me.

===Downloading PDFs===

I tweaked the code to take into account repeat of file names.

===pdf_to_txt_bulk_PTLR.py===

The code must be run in E because of the libraries it uses is not in Z.

I reinstalled pdfminer which might be a problem in the future if the libraries change.

This program converts all pdfs to txt files. It also generates two files _LOG_ERR.txt and _LOG_RUN.txt that includes the names of the pdfs that could not be converted and were converted successfully. Some of the files that were successfuly converted, especially the very small ones, don't have the text from the paper.
