DESCRIPTION

 s = sum(a,dim) : computes the sum of iData objects elements

   @iData/sum function to compute the sum of the elements of the data set
     sum(a,dim) accumulates along axis of rank dim. The axis is then removed.
       If dim=0, sum is done on all axes and the total is returned as a scalar value. 
         In this case, a second output argument holds the error bar.
       If dim='radial', the sum is done radially (R=sqrt(sum(axes^2)).
       sum(a,1) accumulates on first dimension (columns). 
       camproj accumulates on all other axes.

 input:  a: object or array (iData/array of)
         dim: dimension to accumulate (int/array of, or 'radial')
 output: s: sum of elements (iData/scalar)
 ex:     c=sum(a);
