[Ovmsdev] Gas vs. battery metric?

I'd like to add a boolean metric for gas vehicles as a prelude to the phone apps having this info. Would this be ok?

#define MS_V_MOT_GAS "v.m.gas"

ms_v_mot_gas = new OvmsMetricBool(MS_V_MOT_GAS);

The default to false. The other way would be via OvmsMetricInt and an enum (or defines):

typedef enum : uint8_t
  {
  Battery = 0,
  Gasoline = 1,
} metric_vehicle_t;

#define MS_V_MOT_TYPE "v.m.type"

ms_v_mot_type = new OvmsMetricInt(MS_V_MOT_TYPE);

which would allow for more than two types.
