Work/non template container
trafficstars
Create container classes that do not depend on templates.
Notes: This also opens the possibility to have elements that can be created, and deleted, dynamically. However, we do not have a real strategy for the latter so far. Introducing regular d'tors would cause the compiler to add a lot of tear-down code even in "static" sketches, for no good reason. Adding a virtual "destroy()" function, instead, does not seem to solve the problem (compiler does not appear to be able to figure out, when this code is unused).
An additional problem is that ownership of resources (e.g. array of child elements, but also string constants) is not clearly defined. Some of that work will definitely have to be delegated to the user.
One "relief", however, is that EmbAJAX objects really never make sense in a local scope. They'll either live on the global scope, or on the heap, never on the stack. Thus, implict d'tor calls are not really needed at all.
