Skeleton for perceptual text grouping, functionality commented in pseudcode.
Added Delaunay triangulation algorithm which iterates through all text regions to retun text groups.
Further narrowed down types for functions.
Calculate region center function modified to divide a rectangle in half
and return the center Point2f of it.
Added Google unit testing framework along with necessary folders and modifications of Makefile
Moved perceptual text grouping functions into their own namespace perceptual_text_grouping
Modified calculate_region_center to work with Rect of float point type and wrote
a test case for the calculate_region_center function
Merge branches 'perceptual_text_grouping' and 'gtest' into perceptual_text_grouping
Removed debug flag from non optimize target and did a little cleanup for consistent parameter order
Construct planar graph function implemented and tested in main.cpp but currently a test case cannot be created in gtest due to
make test not working  properly resulting in undefined reference to opencv function
Merge branch 'perceptual_text_grouping' of github.com:S-E-D-A/SEDA-CV-TextDetection into perceptual_text_grouping
Fixed makefile to build tests correctly. Object files need to come first. To my knowledge, this is a peculiarity of the version of g++ were using. Later versions aren't so picky but 12.04 doesn't do rolling up dates of g++.
Fixed rect_center_point to translate the center point by x and y and modified the test case.
Switched .gitignore test case name to td_test
Implemented planar graph display with saliency function call, which is currently always true.
Implemented calculation of the normal distribution of the relative minimum distance
and blob dimension ratio to determine text region saliency.

Wrote test case to demonstrate planar graph creation with background saliency pruning.
Enabled -g debugging flag for the test target in the Makefile in order
to allow gdb debugging of test cases
Completed perceptual text grouping by creating a max Rect of connected salient text regions
Visual testcases to ensure functionality of perceptual text grouping
