Time series of rasters shiny module

A shiny module that displays rasters changing in time on a predefined map, with the user choosing which raster should be displayed by using the slider. A histogram summary for each raster choice is also shown.

Arguments

id	An id string that corresponds with the id used to call the module's UI function.
input	shiny server input object
output	shiny server output object
session	shiny server session object
rctRasterList	A reactive that gives a list of rasters to be displayed.
rctUrlTemplate	The reactive url template for leaflet map tiles
rctPolygonList	Reactive list with sets of polygons to be displayed on a leaflet map. # TODO: describe the format of the list!
rctChosenPoly	The user-selected polygon.
defaultPolyName	Name of the polygon to use as the default for mapping.
shpStudyRegionName	Name of the study area region (from rctRasterList).
shpStudyRegionLFLT	SpatialPolygonDataFrame for the study region.
colorPalette	Colour palette to use.
maxAge	Maximum simulation age.
zoom	Initial leaflet zoom.
mapTilesDir	Directory where pre-generated map tiles are stored (default "www/"; note the trailing slash). Be sure to add this dir as 'tiles' using shiny::addResourcePath in your global.R. E.g., shiny::addResourcePath("tiles", "www/All/FULL/map-tiles") (note we don't need the trailing slash here).
mapLegend	The legend text to add to the leaflet map.
mapTitle	Title to be shown above the map.
sliderTitle	Title to be shown above the slider.
histTitle	Title to be shown above the histogram.
nPolygons	The number of available polygons.
nRasters	The number of available rasters.
rasterStepSize	Size of step in the raster slider.
uploadOpts	A list of options for use with file uploads: auth logical indicating whether user is authorized to upload; path a directory path to use for file uploads; user the current username (used for creating user-specific paths). The default for all options is NULL, which means do not use.
rctStudyArea	A reactive SpatialPolygons* object for the whole study area region.
thinKeep	Proportion of points in polygons to keep when thinning or plotting. See ms_simplify.

Value

Invoked for the side-effect of creating a shiny UI.

Reactive polygon selected by the user with the polygonChooser module. Invoked for the side-effect of creating shiny server and UI components. # TODO: reword
