bifacial_radiance 0.0.5

New functionality: Single-axis tracking capability

See /docs/1Axis_tracking_example.ipynb for usage examples.
See /docs/1Axis_Radiance_VF_comparison.py for a comparison with our partner project - BifacialVF (view factor model)

RadianceObj.set1axis(metdata, axis_azimuth, limit_angle, angledelta, backtrack, gcr): import weather file and parse into sub-files based on the tracker angle during those times. Return: trackerdict (dictionary with relevant tracker-specific data)
RadianceObj.genCumSky1axis(trackerdict) : Generate cumulative sky data for each tracker angle
RadianceObj.makeScene1axis(trackerdict, moduletype, sceneDict, nMods, nRows ) : Generate .rad file geometries for each tracker angle
RadianceObj.makeOct1axis(trackerdict) : Generate octfiles incorporating all of the above for each tracker angle
