Feature/tree root

[delboy1978uk]

Now I have set @Gedmo\TreeRoot(identifierMethod="getMenu"), so it can restrict and renumber by the rows with a menu_id of x (the real tree root, a row in another table).

After running the repository method moveUp(7) (the action movie category, in the above example, third out of 3 movie categories), instead of an exception being thrown, now we get:

Oh yeah, i also changed to PSR-4, and moved the source code to the src/ folder standard, which won't affect anything :-)
[EDIT] which I've just realised makes reviewing this code harder. I'll update this on Monday and undo the change from PSR-0, force push and it should be clearer. PSR-4 can go in a fresh ticket :-P

[delboy1978uk]

I tidied up the pull request, code is back in the lib folder so you should be able to review changes easily now :-)

[l3pp4rd]

yes, I would not accept the lib to src change since that would involve BC breaks, since some mapping was directly referenced to directories on configuration for some projects.

could you also add a unit test for this new feature?

[delboy1978uk]

Yeah sure, I can't do it today, but I'll work on it and give you another shout. Regarding the lib folder, we are now on PSR-4 anyway 😃 (just not in src/)

Hi @l3pp4rd I have tested the new functionality and updated the tree.md docs :-)

[l3pp4rd]

thanks for all the effort, hope it will be useful for all users ;)

Hello, I don't see any example in the documentation about having several root, I want to make a system as Wordpress has, what is called Taxonomy, I have seen that in Laravel there are many libraries, but in Symfony none :(
