init()	Overwrite this method if a node needs to do any additional initialization after the standard initialization.
list_dir([data_key])
load(path)	Create podpac Node from file.
probe([lat, lon, time, alt, crs])	Evaluates every part of a node / pipeline at a point and records which nodes are actively being used.
