This patch implements the cylinder pressure calculations for diluent gas in CCR dive computers. This is the third patch for achieving this. The following were performed: 1) Add two lines to try_to_fill_sample() in parse-xml so that diluent cylinder pressures are stored from XML dive log file into structures of sample. 2) Add one line to populate_plot_entries() in profile.c so that the diluent cylinder pressures are copied from structures of sample to structures of plot_info. 3) add three constant #defines in profile.h 4) change populate_pressure_information() in gaspressures.c in order to take into account pressure calculations for the diluent cylinder, calling subordinate functions in the appropriate way. 5) change create_plot_info_new() in profile.c in order to initiate the pressure calculations for the diluent cylinder. 6) Implement two debugging functions (one in profile.c, another in gaspressures.c). These debugging functions are activated by means of #defines. Two function calls dealing with oxygen pressure are currently commented out. They will be activated in the following patch that attends to CCR oxygen partial pressure calculation.
