added thin wrapper around vprintf to allow for clean printing of debug information
gauge field initialization function
import gettime function from tmLQCD, disable 'glock_gettime' mode
add global data structures for libcvcpp, add a global pointer for a fuzzed gauge field, add a global VOL3, add a global pointer for a 'work' spinor field
add APE smearing steps without temporary memory allocation
align io.c and io.h function header for read_ildg_nersc_gauge_field
add functionalities to read_input_parser for libcvcpp
initial commit of libcvcpp, the main data structures are defined and a basic serial version of the code seems to work but some effort still remains
