itaps-parallel tutorial comments

hello vitus,

i just tried out your tutorial. works great .. i had just a few  
hickups (see below)! i think your "Zoltan" would be a good fit after  
"Hello" and before "Smooth". Maybe you could create a single directory  
for the two exercises similar to the structure of "Hello" and "Smooth" ?

below are my comments for the two tutorials

cheers

comments for tutorial1
======================

- in EXERCISE 3 it took me  while to figure out to use argv[2]

- when i type 'make' it wrongly tells me

    "To build the iMeshPZoltan C++ test program, type
       gmake ZOLTAN_ARCH=desired_arch fmdbzoltan"

- you should add the following variables to EXCERCISE 4 unless you  
left them out on purpose

   int parts_size, parts_allocated = 0;

- in the Hands_on file it should say to run. not the added './'

   mpirun -np 4 ./fmdbzoltan 4 part.sms REGION tmp

comments for tutorial2
======================

- change comment "delete the partition" to "destroy the partition"

- change comment "delete the part" to "destroy the part"

- if the user does not use "VTK" as option in iMeshP_saveAll and then runs

    mpirun -np 4 ./fmdbzoltan 4 part.sms REGION repart

the code crashes. instead the user should call

   mpirun -np 4 ./fmdbzoltan 4 part.sms REGION repart.sms

which will work either way.
