// TODO: add divFlag for inheritance Mother Class (ClassName) should be add to children (className)=>nameOfObject.class(ClassMother,ClassDaughter) @Boris
// TODO: perhaps, we should use some aliases? @Marian
// TODO: may be we should also use TVectorD or TMatrix instead enumeration? @Boris
// TODO: extend to TH2D, TH3D @Boris
// TODO: think how to combine  AliPainter::ParseString and AliPainter::ParseOptionString @Boris
// NOTE: we can provide list of brackets and remove ignoreBrackets from arguments. mb just add flag about do you want to ignore brackets or not.
// TODO - now we have 2 steps for parsing of ranges option to array of string with simple range values. 1. Initial string into map. 2. Map into array fo strings. First of all we can use vector of vector instead map, and the second we should think how we can avoid this 2 intermediate steps with map. @Boris
// TODO: add few classes with []
// TODO: change global maps to arguments of functions
