-Refactored 'attachX' methods into 'plugXIntoInput', to further clarify
usage;
-Made the PositioningAnalyser instantiable without receiving the
AutoGaitModel: still needs to have it initialized afterwards, or won't
work;
-Begun creation of LatLong and XYZ coordinate conversions (tests won't
pass due to lack of precision in relation to MatLab results);
