Resturcted the project directory
Added the semi-lagrangian code to repository
WORK IN PROGRESS
Added the functionality to interpolate values of different trees with arbitrary tree depths from each other
BUG FIX by interpolation of tree values
Added the tree_data class which performs various operations on the data of tree
Merge branch 'mdimtreedata' into semilag
Added the functionality to clone a tree structure
Added the functinality to combine (collapse) multiple trees into one tree with multidimensional values
Restructre the semi-lagrangian code to integrate easily with tree code
Seperating the interpolation functions and minor changes
Modularizing the semilag code. Many functions are now more robust.
Minor changes of tree nodes visualization
Finished the simulation of advection with semilag on qtree. Some fixes are still needed.
Added the functionality to provide a separate function to compute the interpolation values outside the interpolation domain
Added the functinality to interpolate the values of some arbitrary points inside a tree domain
FINISHED the Semilag on a quadtree with TIME-INDEPENDNET velocity field
BUG FIX
Minor modification to tree data visualization
