Spatial average over X and/or Y of a vector/scalar field

FF = spaverf(F) computes the spatial average of the vector/scalar 
field F.  FF is a uniform vector/scalar field. If F is an array of 
fields, spaverf(F) computes the individual spatial average of each 
FF = spaverf(F,AXIS) averages over the AXIS direction, where AXIS is 
'X', 'Y' or 'XY'. Default is 'XY'.  FF is a vector/scalar field uniform 
in the AXIS direction. 
By default, spaverf considers that the zero elements of F are erroneous, 
and does not include them in the computations. If however you want to 
force the zero elements to be included in the computations, specify 
If no output argument, the result is displayed by showf.
