Test code to follow.

Modify regular expression in format.py
Updated plots with no legend option and no border

Plots can be generated with optional legend. Blocks have no black
border (cleaner viewing of small segments).
Updated Tables and formatting

Rewrote list and table formatting code;
t-test also generates sorted abundance table and absence list per
sample.
LaTeX tables formatting has more options.
Change regex to make it </path> inclusive
Add check to stdout and stderr for the subprocess

There's sometimes useful information that inkscape gives back in case
something is failing.

Merge pull request #8 from ElDeveloper/regex

:cake:
Add code to remove background rect from print

The background rect object that was found in the SVG formatted files was
there given the fact that Emperor allows you to set the background color
for the print. If we leave this object in there we cannot use Inkscape's
fit to drawing area functionality.
Change inkscape command call to crop the prints

Prints are now cropped to be the size of the area these are using only.

Print cropping
I am adding the LaTeX files.
These are the accessory files for template.tex to work:

macros_xxx.tex - should be in the same directory as template.tex
pdfs/ - this directory containing image files should be in same directory as template.tex
    - legend files should be same for every individual, but legends 2 and 3 still need tweaking
    - ovals file should be same for every individual, but it's exact postitioning will change based on final figure1
    - headerbw should be replaced with the original from Adobe document
    - figure4 should be done with Helvetica to match legends

IMPORTANT: For fonts to work, template.tex must be run with LuaLaTeX (or possibly XeTeX) preferably on a Mac that has Futura font installed.
