Wrong naming of PFC files for B4 configuration

[lasofivec]

I tried to construct the new ITER configuration "B4" by doing the following:

In [2]: configB4 = tf.geom.utils.create_config("B4")

and got

              TFG_PFC_ExpITER_BLK10.txt
              TFG_PFC_ExpITER_BLK17.txt

The reason for this is error is that when loading the files it will match any file starting with PFC and containing BLK1 in the name of the file. So it matches many additional files.
This is easily solved by renaming the file

TFG_PFC_ExpITER_BLK1.txt

to

TFG_PFC_ExpITER_BLK01.txt

as well as all names of BLK files with number $<10$ and respectively update in tofu/geom/utils.py the name of the elements.

yes, that's right. I noticed the error also, and I already changed them tp this commit:

could you make sure if this would be fine?

[lasofivec]

It's almost there :)
I added a couple of comments on each commit. Could you take a look please ?

PS: could you also do a pull request of this branch into devel ?
