* Group text lines if they are centered (#382)
Closes#382
* Add comparison private methods to LTTextLines
* Add missing docstrings
* Add tests for find_neighbors
* Update changelog
* Cosmetic changes from code review
* Default value for --all-texts should be false, because using the flag enables it
* Fix edge case: when no neighbors are found a line should form its own text box
* Added test for grouping textlines where 1 is outside the parent bounding box
* Added CHANGELOG.md line
* Remove scaling font height/width with size of font bounding box
* Refactor LTChar bounding box computation
* Change expected outcome of `python tools/pdf2txt.py samples/simple3.pdf`, because it looks like an improvement. However, when I view `samples/simple3.pdf` I don't see any text at all. The change in expected outcome is explained by the fact that the bounding boxes of characters can be different, depending on the `/FontBBox` parameter of the font.
* Add test for font sizes, and for this a high-level function that returns an iterator of LTPage objects
* Add line to CHANGELOG
* Drop support for legacy Python 2
* Add python_requires to help pip
* Upgrade Python syntax with pyupgrade
* Upgrade Python syntax with pyupgrade --py3-plus
* Python 3 imports
* Replace six
* Update CONTRIBUTING.md
* Added line to changelog

Fixes#171Fixes#199Fixes#118Fixes#178
Added: tests for building documentation and example code in documentation
Added: docstrings for common used functions and classes
Removed: old documentation
Changed: using a heap instead of a SortedList and avoid rebuilding the heap in each iteration
Changed: avoid potentially huge number of variable assignments in list comprehension.
Changed: avoid repeatly evaluating `obj is obj` in list comprehension by storing id(obj).
* added color support to stroking and non stroking color spaces
* extended LTCurve, LTLine and LTRect to save painting information
* modified PDFLayoutAnalyzer to populate the shapes with painting information
* Removing all the "#!/usr/bin/env python" lines, they do not need for python3, solving issue number: #19.
* Restored all the shebangs in the tools and tests folders (because they are real executables) but used "#!/usr/bin/env python" instead of "#!/usr/bin/python" as this blog points out: https://www.peterbe.com/plog/importance-of-env
Removed also the shebang from pdfminer/psparser.py file.
This commit finds horizontal neighbors in a horizonal line and merges them together into a single horizontal line if necessary. This leads to much better text extraction if the PDF was created in a funky way.
For example (test case coming), I have seen PDFs which are written almost like vertical columns, but the text is entirely horizontal.
1.
When detecting text in a horizontal line, we already add a space between words if separated by more than word_margin apart. However now, we only do it if there is not already an existing space. This prevents multiple spaces being placed between words.
2.
Detect a horizontal line if the line is zero width. This improves our detection of horizonal lines when looking for both horizontal and vertical.
3.
Don't detect a vertical line if the previous letter is whitspace. Prevents double spaces being caught as vert lines.
4.
Improve upon an unfortunate O(N^2) algorithm which I have seen taking many minutes to execute. Unfortunately, while the "fix" reduces algorithmic complexity, it isn't technically correct, so we only do it when we know things will take a long time.
