In dmrg_solve2 commented the compression of the local 2D matrix (bydlocode: it seems to make a convergence in
sPDEs slower?)

Added a "zoo" with .mat files containing the data from the examples showed in dmrg_solve paper in "tests/"
The general file name is follows:
	dmrg-solve_ex<nnn>.mat,
where <nnn> is an example number.
In some cases (if an example contains several tests indeed), I used extended format:
	dmrg-solve_ex<nnn>_<eps>-<d0>.mat,
eps - compression accuracy, d0 - quantics dimension.
These files contain QTT matrix A, rhs and DMRG solution x
Preved, Serega!!!!!! Privozi zhenschin!!!
One more constructive commit =).
I've added the MEX routines to read/write tt_tensor from/to the SDV format.
To save a tt_tensor, run tt_save in @tt_tensor directory.
To load a tensor from a file, run tt_tensor('filename') (is is implemented as a constructor)

PS: in addition to Dima's tt header, now the item head.inf[1] contains double/single/real/complex flag of the
core data stored:
	0 - double real,
	1 - double complex,
	2 - float real,
	3 - float complex.
PPS: one more small addendum: @tt_tensor/full now accepts a size vector as the second argument ('cause I fed up
with lines like "mesh(reshape(full(a), sososo))", now one can write "full(a, sososo)").
Moved this to core
Added .mex for the MAC
Cleared something: it seems that accidentally
tt_compr2.m did not include the latest changes
As was the tt_mat_compr
However, I would like to recommend to use "round" whenever possible
Added TT-Toolbox 2.0 version for the test files.
Also copied them to the repository of Oseledets-Dolgov article
Deleted test files with the old format (since the main reason
is to put them on the web "more user-friendly format" is OK)
Deleted some unused files
Small commit
Again, something deleted
Final fixing in the "master" branch
Then I will create TT2.1 branch for the next ("more clear") release of the Toolbox
This commit creates a cleared version of the Toolbox to be designated
as TT-Toolbox 2.1
This is a clean "Release candidate" for the TT-Toolbox 2.0
I have removed the directory "cross" since it is unsystemized and not well-documented
Small commit
One more small commit
In future, may fill with more examples
	deleted:    matrices/mat_fokker.mat
Tweaking the interface of the dmrg_solve2
Added an experimental file with the Fokker-Planck problem
Downloaded lobpcg from Matlab Central
New test file test_full_KN for timedep.
small fixes
