WIP parallels tests, fix example input folder, bug fixes

-- added tests for parallel sections (bridles etc)
-- removed examples input folders, fixed directory
-- bug fix loading EA for parallel sections, now forces to be floats
-- working on bug fix for relocation of shared anchors when loading if span is slightly off
   (working to recalc span so anchor loc doesn't change since it's explicitly defined in ontology)
-- cable bug fix make sure connection location is at depth relative to platform depth
