introducing meta_tree

I finally got some time to implement a small amount of my meta_tree project.
meta_tree (always lowercase) is an NT-only implementation of my own file-meta-data managing-software.
It gives you the possibility to add meta-data ("tags") to your files.
It is aiming for people who are organizing their data heavily on folders and find it difficult to find and reorganize their structure to changing needs.
meta_tree will allow you to use tags on their files and search and reorganize their files depending on this tags.
