Summary description: Adds forward-referencing functionality to the cleveref package

Announcement text:
----------------------------------------------------------------------
Imagine you are reading a long mathematical text such as a text
book or a thesis.
There are plenty of supplementary lemmas, propositions, theorems
and/or exercises throughout the whole text.
You ask yourself 
"Gosh, while Lemma 1.12 is certainly an interesting result
 _where_ is this result used later on in this long text?
I really would find that helpful to decide _why_ I should
read the proof."
You can, of course, use the PDF search function of your viewer
to look up the string "Lemma 1.12" but wouldn't it be more helpful
if Lemma 1.12 already indicates all or at least its most useful/
crucial applications via an info message?

This is what the package cleveref-usedon tries to address.
The info message "Used on p. 40, 43-45 and 101." would then
be printed to the header of Lemma 1.12.
This is done by extending the \cref and \Cref commands
and giving them an optional argument 'UsedOn'.
Every time you wish to record a reference in the 'used on page
list', you would simply type \cref[UsedOn]{<LabelName>}.
If you use \cref without this optional argument, this
reference won't be recorded in this page list.

Check the package documentation for more info on the usage
or look at an example directly.
