/**
 * This file contains macros and classes that can be used to conveniently implement classes that store the data of an arbitrary count
 * of additional lists within the same memory block directly behind the class data, in a way that one the whole data can be stored by one copy-operation
 * to another place, like needed in ItemRepository. These macros simplify having two versions of a class: One that has its lists attached in memory,
 * and one version that has them contained as a directly accessible KDevVarLengthArray. Both versions have their lists accessible through access-functions,
 * have a completeSize() function that computes the size of the one-block version, and a copyListsFrom(..) function which can copy the lists from one
 * version to the other.
 *
 * @warning Always follow these rules:
 * You must call initalizeAppendedLists(bool) on construction, also in any copy-constructor, but before calling copyFrom(..).
 * The parameter to that function should be whether the lists in the items should be dynamic, and thus most times "true".
 * You must call freeAppendedLists() on destruction, our you will be leaking memory(only when dynamic)
 *
 * For each embedded list, you must use macros to define a global hash that will be used to allocate the temporary lists, example fir identifier.cpp:
