#  [ host_tuple ]    # list of host data

#
#  command_results = {cpu_id: data_output}       # contains a dictionary, one set of data for each cpu
#
# For example:
# returned data     = [ cmd_output1, cmd_output2 ... ]
# cmd_output1       = { cpuid1 : cpu_output1, cpuid2 : cpu_output2 ... }     # cpuid is "None" if there was only one cpu used
# cpu_output1       = { candle1  : profset_output1, candle2 : profset_output2 ... }
# profset_output1   = { profset1 : profile_output1, ... }
# profile_output1   = { profiletype1: step_output1, ... }
# step_output1      = { step1: list_of_cpu_times, ... }
