d71133a769 Use ocrx_cinfo to hold character box and confidence information 
With hocr_char_boxes enabled in hocr output, each grapheme now gets
its own span tag, which holds the character confidence and box
coordinates. Using x_bboxes at the ocrx_word level was
inappropriate, as it was impossible to find which grapheme was
represented by each bounding box.

06b7a7b188 Add option to include character bounding boxes in hocr output 
Add the 'hocr_char_boxes' configuration option (off by default),
which enables printing the bounding boxes of each character in the
x_bboxes property of an ocrx_word element in hocr output.

ea401c9046 Only generate dir for HOCR when needed - fixes #208 
Takes advantage of inheritance and dir="ltr" default to:
 - only generate paragraph dirs which are not ltr
 - only generate word dirs which don't match enclosing paragraph

Tested against LTR, RTL, and mixed direction files. Files for the
latter two cases are in a separate commit on the ltr-test-files branch.

431786276c INCOMPATIBLE fix to hOCR line height information - fixes #225. 
This fixes the duplicate line IDs caused by inserting height information
into the middle of the ID and it moves the line height info into
the title attribute like everything else, rather than using non-standard
HTML attributes (which won't validate).

This change may break consumers of the HTML output, but 3.04 has only
been in the wild for 6 months and the current HTML is invalid, so I 
believe the benefit outweighs the cost for the fix.

53fc4456cc Fixed issue 1252: Refactored LearnBlob and its call hierarchy to make it a member of Classify. 
Eliminated the flexfx scheme for calling global feature extractor functions
through an array of function pointers.
Deleted dead code I found as a by-product.
This CL does not change BlobToTrainingSample or ExtractFeatures to be full
members of Classify (the eventual goal) as that would make it even bigger,
since there are a lot of callers to these functions.
When ExtractFeatures and BlobToTrainingSample are members of Classify they
will be able to access control parameters in Classify, which will greatly
simplify developing variations to the feature extraction process.
