Schedule a homogeneous scaling process (i.e., exponential growth or decay) across the entirety of a specified continuum layer.
|coefficient||Double||The coefficient by which to scale all values on the layer.|
|layer||String||Continuum layer upon which to schedule scaling process.|
|period||Integer||Waiting period between occurrences of this process. period=0 means do only once.|
|start||Integer||Time at which to begin executing this process (specified in integration cycles).|
