An internal function that detects the events according to the heatwave definition, and joins across the gaps if desired.

proto_event(t_series, criterion_column, minDuration, joinAcrossGaps, maxGap)

## Arguments

t_series A dataframe of the correct dimensions inherited from detect_event within which this runs. The column to use for the detection of events. Minimum duration for acceptance of detected events. This logic gate tells this internal function if it should connect events across the maxGap (see below). The default it inherits is TRUE. This is the number of rows (days) across which distinct events will be combined into one event if joinAcrossGaps = TRUE.

## Value

A dataframe that will be used within detect_event, or which can be returned by detect_event if the switch 'protoEvent' is specified as TRUE.
