added a todo note
Revert "added a todo note"

This reverts commit 0b1fbb172eda27e81d463115b0fdff012a134ab1.
reverting to before the screwing up

before moving the library dependencies
working version of swipped tabs -library included

the library files are now directly included in the project (and in the
git folder)
the page content is now empty

in TestFragment, removed the string content (which was generated from
the titles (array of strings))

now we need to understand how to use the guy's java classes to get the
tabs we want (black background, blue underlined tabs etc.)

I will file a task on chili - because I don't think I will be able to do
this in a time efficient manner (someone who has a better knowledge of
the sdk's standarrd classes should do it).
android library re-added

that jar file was deleted when we were using the external library
now that it is included directly in the [project we re-copied it where
it was originally.
