made a branch: Slicing

To work only on the slicing algorithm
cuting with y1

iterating through each piece left of x1, and cuting with y1.
Still need work on how to group all the groups(good for z1) made by y1
cuts on each x1 cut pieces
group for z1

after y1 cut, the group is ready(hope so) to be sent to be cut by z1
group for z1 ready

after iterating on all pieces produced by y1 for each piece produced by
x1.... we have a group to be sent to be cut by z1
working on slicing alg

making all the code more stable and corectly nested.
About to start working on the z1 slicing part.
separated xSlicing from ySlicing

created seperate funcitons for x slicing and y slicing.
on this commit it is still a PROBLEM, memory allocation to save alements
for Y2 and Z.
but it runs a draws the object after y1 cut
still working on ySlicing

fixed a little xSlicing
still stuck on how to finish ySlicing correctly
more ySlicing

trying to make temp group[] for re-Y and Z, for yes-cut and no-cut
possibilities.
next step is to unite this temp group[]s (2 for re-Y) (2 for Z)
and make sgCGroup with them, and send them to the corresponding
functions.
working on ySlicing and zSlicing

ySlicing still needs to group and send pieces to re-ySlicing turn++.
ySlicing is packing correctly the pieces for zSlicing.
ySlicing is taking into account no pieces for zSlice
started zSlicing separate function
modified xSlicing a little

to include turns and cube part
started intersection with cubes

new algorithm, do slicing of object, using boolean intersection of
27(26) cubes
implemented slicing using cubes intersection

simple algorithm using intersection to get all the desired objects of
each cubie in one boolean operation .
updated classes to use new cutter

wrote new constructor code for the cutter
starting to create cubes
updated Visual Studio project file

Now it has relative path linking to lib and h files of the sgCore
library
Merge pull request #1 from nelsonbss/slicing

Updating Visual Studio Project file, to have relative paths to .h and .lib files of the sgCore library
