Prepositions and "There is..."

I have just improved the Prepositions Section on the Basic Spanish document. Below, above, in front of...will never be a problem now.
Also added new vocabulary about Nature and Animals on the Vocabulary document. Hope you "enjoy" the changes. Please, if you have any suggestion to make, they are more than welcome.

Now is a little grey in Puli but the Sun will soon shine, don´t give up :-)
