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
