[svn-r14437] bug fix for h5dump subsetting (deal with blocks)and new test runs

add a check for block overlap after the command line parsing

* Algorithm
 *
 * In a inner loop, the parameters from SSET are translated into temporary 
 * variables so that 1 row is printed at a time (getting the coordinate indices 
 * at each row).
 * We define the stride, count and block to be 1 in the row dimension to achieve 
 * this and advance until all points are printed. 
 * An outer loop for cases where dimensionality is greater than 2D is made. 
 * In each iteration, the 2D block is displayed in the inner loop. The remaining 
 * slower dimensions above the first 2 are incremented one at a time in the outer loop
 *
 * The element position is obtained from the matrix according to:
 *       Given an index I(z,y,x) its position from the beginning of an array 
 *       of sizes A(size_z, size_y,size_x) is given by
 *       Position of I(z,y,x) = index_z * size_y * size_x 
 *                             + index_y * size_x
 *                             + index_x
 *
