VPT2-screened PyVCI Files

This is an example of a module for changing the endianness of each word in the
backup vci_matrix file. 

First, clean the directory of old files,

./make_clean

Then, convert "reverse_byte_order.pyx" to C using Cython, by calling

python setup_cyth.py build_ext --inplace

which will do the conversion and compilation. If there are 
problems with the generated C code, than try using one of
the versions supplied in "code/C_code_Py27" or "code/C_code_Py34",
which were converted with Python2.7 and Python3.4 respectively.

After that, assuming you have your vci_matrix with the wrong
endianness in the same directory and under the name "fin", call

./change_endianness.py fin fout

"fout" is the name for the new backup file, with byte order of each float and int
reversed.
