[svn-r7813] Purpose:

h5diff new feature


Description:

added compare for attributes
a new options flag (-a) was added to the options structure. it is 0 by default (no compare )
the output of the compare is the same that for datasets, and all the other flags also apply for attributes
(the memory compare is done in the same function diff_array)
all the other requirements for compare of datasets (type, space) are identical too




Platforms tested:
linux
solaris 2.7
IRIX
