Added class DSetAccPropList

Browse Source 
Description:
    - Added class DSetAccPropList for the dataset access property list.
    - Added wrapper for H5Dget_access_plist to class DataSet
        // Gets the access property list of this dataset.
        DSetAccPropList getAccessPlist() const;

    - Added wrappers for H5Pset_chunk_cache and H5Pget_chunk_cache to class
      DSetAccPropList
        // Sets the raw data chunk cache parameters.
        void setChunkCache(size_t rdcc_nslots, size_t rdcc_nbytes, double rdcc_w0)

        // Retrieves the raw data chunk cache parameters.
        void getChunkCache(size_t &rdcc_nslots, size_t &rdcc_nbytes, double &rdcc_w0)

    - Added two more arguments to H5Location::createDataSet:
        const DSetAccPropList& dapl = DSetAccPropList::DEFAULT
        const LinkCreatPropList& lcpl = LinkCreatPropList::DEFAULT

    - Added one more argument to H5Location::openDataSet:
        const DSetAccPropList& dapl = DSetAccPropList::DEFAULT

Platforms tested:
    Linux/64 (jelly)
    Linux/32 (jam)
    Darwin (osx1010test)

4. This section shows the differences between the old and new methods
for allocating the following constants
- PropList constant, PropList::DEFAULT.
- DSetAccPropList constant, DSetAccPropList::DEFAULT.
- DSetCreatPropList constant, DSetCreatPropList::DEFAULT.
- DSetMemXferPropList constant, DSetMemXferPropList::DEFAULT.
- FileCreatPropList constant, FileCreatPropList::DEFAULT.
- FileAccPropList constant, FileAccPropList::DEFAULT.
- LinkAccPropList constant, LinkAccPropList::DEFAULT.
- LinkCreatPropList constant, LinkCreatPropList::DEFAULT.
- ObjCreatPropList constant, ObjCreatPropList::DEFAULT.
For these constants, the library has the same changes, except the
class names and the HDF5 corresponding constants. Only the items
of PropList are listed, and "PropList" can be replaced by any of
DSetCreatPropList, DSetMemXferPropList, FileCreatPropList,
FileAccPropList for those classes. The HDF5 C constant "H5P_DEFAULT"
can be replaced by any of these respectively: H5P_DATASET_CREATE,
H5P_DATASET_XFER, H5P_FILE_CREATE, and H5P_FILE_ACCESS.
