Computation of mean relative diffenence and standard deviation for station / sensor network.

1	smp_MRD(data)

data

zoo object, containing measures of a variable, e.g. volumetric soil moisture content

`MRD`	mean relative difference for each realisation (station / sensor)
`SDRD`	standard deviation of reltive difference for each realisation (station / sensor)
