The transition from a single fragment, which is a tree, to a polymorph
fragment implemented by a base class (Fragment) and a subclass for
storing the tree (NodeFragment) and another subclass for storing text
(TextFragment) is now considered complete.
What is still missing is the proper treatment of embed text. This should
be indented and breaked at 72/79/80. Also newlines and special chars
should be replaced on generation, maybe also giving some way of
preventing XSS. Regarding the NodeFragment there should be some
adjustments to further adjust the styling, which of course should also
be reflected by TextFragment. This should also include the generation of
self-closing tags. Furthermore the html generation should be based on a
single text object, to which is added to. This will later on also enable
to directly send generated parts over the network while still generating
some data.
But all this changes are to meant to change the behaviour of existing
classes, so the will be eventually implemented on seperate branches.
