Plot monotone

1	plotMonotone(climate, cluster, dayType, variable)

`climate`	`data.table` climate file, 2 first columns are Date and Period, others are params files
`cluster`	`data.table` output of clusteringTypicalDays
`dayType`	`numeric` typical day
`variable`	`character` name of variable to plot

# climate data
climate <- fread(system.file("dataset/climate_example.txt",package = "flowBasedClustering"))

# classification result
clusterTD <- readRDS(system.file("dataset/cluster_example.RDS",package = "flowBasedClustering"))

plotMonotone(climate = climate, cluster = clusterTD, dayType = 1, variable = "DE_wind")
