[svn-r229] New examples have been created in the examples directory:

    h5_write.c    - stores INT array as INT32 little endian dataset in the HDF5 file.

    h5_read.c     - gets info about the dataset;
                    reads hyperslab from the dataset in the file into
                    2-dim slice of the 3 dimensional array.

    h5_compund.c  - creates compound dataset and writes it to the file;
                    reads subsets of the dataset.

    h5_extend_write.c - writes extendable dataset.

    h5_extend_read.c  - gets info about the dataset;
                        reads dataset and one of the chunks.
