def parse(tree, parse_funcs):
"""Parse placeables from the given string or sub-tree by using the
parsing functions provided.
The output of this function is **heavily** dependent on the order of the
parsing functions. This is because of the algorithm used.
An over-simplification of the algorithm: the leaves in the ``StringElem``
tree are expanded to the output of the first parsing function in
``parse_funcs``. The next level of recursion is then started on the new
set of leaves with the used parsing function removed from
``parse_funcs``.
:type tree: unicode|StringElem
:param tree: The string or string element sub-tree to parse.
:type parse_funcs: A list of parsing functions. It must take exactly
one argument (a ``unicode`` string to parse) and
return a list of ``StringElem``s which, together,
form the original string. If nothing could be
parsed, it should return ``None``.
