Changed filename bug in PD_beta_epochs_rel...by_dp_ind_avg.m; started changes to Carb_data_phase_figure.m.
Changed Carb_data_phase_figure.m to plot phase differences in degrees, not radians.
Changed bin size; changed epoch size in PD_beta_epochs_rel_infusion.m.
Among other small fixes, debugged beta epoch selection from Michelle's code.
Merged with master.
