Next up is basal rate stuff.  This is taken from the following data line:

```
142,10/5/13,21:34:37,10/5/13 21:34:37,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,BasalProfileStart,"PATTERN_NAME=standard, PROFILE_INDEX=4, RATE=0.4, START_TIME=37800000, ACTION_REQUESTOR=pump",11528764570,AABBCCDD,173,Paradigm Revel - 523
```

```
{
  deviceTime: '',
  schedule: 'standard',
  index: 4,
  start: 37800000,
  rate: "0.4",
  type: 'basal-segment-rate' // or basal-start or something or whatever
}
```

If I understand this correctly, it signifies a change in the basal rate that the pump is delivering?  I.e. it is the "edge" (both end of previous and start of its own) of a basal segment as the visualization wants it.

If so, what do you think of "basal-rate-change" as the name of the event?  Also, what is the expected relationship between the deviceTime and startTime?  I was assuming that the startTime is just an offset from midnight which means that the deviceTime should be `midnight + startTime` (or 10:30 in this instance), but the timestamp on the row doesn't actually line up with that.  @bewest @jebeck do you know?
