Refactors internals...
Refactors internals * rewrite axisUpdated signal handling * create handlers for each property of axis * decouple chartdataset, presenter, theme * adds theme manager * adds axis add/remove/attach/detach handling * refactors createGraphics * add initializers (graphics,domain,theme,animations) * refactor the way the charts are constructed (decouple form presenter) * fix initialization issues with qchart * refactor domain logic to handle also geometry size for charts * delegate xyseries geometry calculation to domian * fix lazy initialization of animations * remove hadnleGeomoetryChanged * add shared pointers to handle reference count for domain * moves nice number algorithm to domain * adds applyNiceNumbers(), depreciate setNiceNumbers * refactor multiple charts handling * domain is shared object * each domain can have multiple axis for controlling * multiple charts share now the same domain
