`pathInputs`	Default NULL (TODO: description needed)
`variables`	Character string of the variables to be used, i.e. c("PPT", "Tmax").
`years`	Character string of the years to use. i.e. c(2011:20100).
`GDriveFolder`	Character string of the folder in google drive to upload the layers to. Handy for shared projects.
`climateFilePath`	Character string of the path to the climate file in google drive (i.e. "https://drive.google.com/open?id=1wcgytGJmfZGaapZZ9M9blfGa-45eLVWE" for 'Canada3ArcMinute.7z')
`fileResolution`	Character string of the for naming purposes (i.e. '3ArcMinute')
`authEmail`	Character string of googledrive e.mail for authentication for non-interactive use.
`RCP`	Character string of RCP to be used (i.e. '45')
`climateModel`	Character string of climate mode to be used (i.e. 'CanESM2')
`ensemble`	Character string of climate ensemble to be used (i.e. 'r11i1p1')
`rasterToMatch`	RasterLayer template for these layers to match
`studyArea`	shapefile of study area
`model`	For naming and shortcut for variables: ie. 'birds' or 'fireSense'. If you wanna provide the variables to be produced, don't use birds or fireSense here.
`doughtMonths`	numeric. Months for fireSense to calculate MonthDoughtCode (MDC) i.e. '4:9'.
`returnCalculatedLayersForFireSense`	Logical. Should it calculate MDC (TRUE) or return the original variables (FALSE)? Default is FALSE.
`yearsWithClimateProjections`	Numeric. The user can pass the years that have climate projection in the data. Default to 2011:2100.
`overwrite`	logical. Default to FALSE. Should the layers be overwritten if exist?
`overwriteOriginalData`	logical. Default to FALSE. If changes happen in the original layer (the one provided in climateFilePath), set this to TRUE to overwrite the zip files downloaded.
