usage: varb2 = zproj(varb1,op)

ZPROJ combines all the values within a z-column of VARB1 (i.e., all Z values that would project onto a single point in the XY plane) into a single value in VARB2, thus reducing a solid variable to a matrix. Z-column values are combined according to the operator, OP, which can be any of:

                MAX, MIN, SUM, MEAN, or STDEV

Examples:

        mat1 = zproj(sol1,max)      ; convert solid to matrix of z-column maxima
        aray1 = zproj(mat1,mean)    ; find mean of each z-column
