function Program_Pump(h_pump,which_dir,volume)
%% Add_Dye
% This function programs the syringe pump to add or remove dye solution. To
% run this program on the pump use h_pump.sendcmd('RUN'); in Matlab
%
% h_pump is the handle of the pump returned from pumpsBen
%
% which_dir determines if the pump adds (infuses) or removes (withdraws)
% dye solution.
% To add (infuse)      set which_dir = 'add'
% To remove (withdraw) set which_dir = 'remove'
%
% volume is the amount of dye to be added or removed. Units are mL
