Merge pull request #105 from gem/svir-viewer-extend

Svir viewer extend
leaflet_base.html - remove some unsued JS libs
data_viewer_base.html - add the dj js lib
data_viewer_base.html add the radar chart D3 js lib
include the d3 js libs
svir_viewer.js - remove the highcharts and replace them with d3 spider charts, IMHO the spider charts are more difficult to interpret, maybe another kind of chart should be used instead
svir_viewer.js - add dynamic chart legends
update the radar chart lib to improve legibility
after much experimenting with D3 a working spider and bar chart
added lib used for the spider chart
svir_viewer.js - update the bar charts to render into multiple category tabs
include the health and infrastructure categories
switch out the spider chart for a line chart
work in progress
