Moved non-functioning cross to oldcross directory
core/tt_ind2sub.m, core/tt_sub2ind.m: vectorizations
cross/amen_cross.m: smart index/functional input
cross/multifuncrs2.m: just calls amen_cross
new file:   solve/alstpz_solve.m: ALS(t+z) implementation
solve/amen_solve2.m, solve/dmrg_solve3.m: testdata is populated only after the last block (mem savings).
greedy2_cross is commented and published
fixed a typo in amen_cross, which failed multi-input calls
Set multifuncrs type by default - svd
amen_cross: set by default zrank=5 (as in multifuncrs versions),
and zrank2 = zrank/2: we need the secondary random enrichment for z, if the tensor is too bad.
Such as the sum of delta-functions =)
rename startup.m -> setup.m
Matlab tries to parse "startup" by its own insight, and predictably fails
fmex Makefile.in is modified such that "default" compiles the 8-byte ints correctly
defaults in dmrg_eigb changed to (hopefully) more robust
amen_solve2,dmrg_solve3: small poking around convergence output (you
will not notice that unless verb==3).

dmrg_eigb: added rmax parameter

lobpcg: somehow I've accelerated it several times by removing clear and
condition estimate commands.
With modern memory resources you may forget about the former,
but keep in mind the latter when working with generalized eig-problems.
