FILLPREVIOUS
bucketize
gts
The FILLPREVIOUS function fills gaps in a bucketized Geo Time Series™ instance by re-using the value/location/elevation
of the previous non empty bucket to fill each empty bucket. It expects a GTS or a list thereof on the top of the stack.
This function has no effect on non bucketized GTS instances.
