Initial commit with very rough framework for the graph display controller.
Added json placeholder directory in the "static" directory.
Initial creation of the view for the graph display.
Initial creation of the graph view to display the D3 generated visual of comparison graphs of the taxonomy the given stree.
Added conditional check to confirm that the desired JSON is present. Cleaned up the code base in general as well.
Merge branch 'master' of https://github.com/OpenTreeOfLife/phylografter into d3display
Added initial function to accurately grab the JSON file for the tree of choice, and pass it to the view.
Added the ability to parse the JSON string from the controller. Since D3 requires the data to be an Object, and it comes in from Web2py as a string, had to use =XML parsing and eval() function to convert it back to an object before D3 would display it.
Added test .JSON file for tree 209.
Cleaned up the view() function. Removed unecessary returns. Also corrected an issue by switching graphlist.extend to graphlist.append to simply the result for processing in the view.
Modified so that the link to view the graph is conditional on there being a JSON file in static/json/ for the tree in question. If the file does not exist, the link will not display.
Added an additional JSON test file from tree 208 to further test display options.
Small changes to help clean up the view, and reduce the unecessary code in the view.html file.
Layout fixes for d3 figure in graph-view page

Moved the svg into the 'div.span9' column above (selected by jQuery).
Added a subtle border to set off the svg, and linked the CSS for this
page. Adjust the svg width to fit within the main page area.
Additional clean up to stream line the UI for the treegraph addition to phylografter.
Ignored the treegraphjson directory.
Modified the read directory so that the controller will correctly locate the JSON files under static/taxonomy-stree-json/
Added /static/taxonomy-stree-json/ removed /static/treegraphjson/
Fixed a typo in variable name causing an error.
Added functionality to display link to OpenTree Graph if its present.
