ENH: ndim tables in HDFStore (allow indexables to be passed in)
- ENH: changes axes_to_index keyword in table creation to axes
- ENH: allow passing of numeric or named axes (e.g. 0 or 'minor_axis') in axes
- BUG: create_axes now checks for current table scheme; raises if this indexing scheme is violated
- TST: added many p4d tests for appending/selection/partial selection/and axis permuation
- TST: added addition Term tests to include p4d
- BUG: add **eq** operators to IndexCol/DataCol/Table to comparisons
- DOC: updated docs with Panel4D saving & issues relating to threading
- ENH: supporting non-regular indexables:
  - can index a Panel4D on say [labels,major_axis,minor_axis], rather
        than the default of [items,major_axis,minor_axis]
  - support column oriented DataFrames (e.g. queryable by the columns
- REMOVED: support metadata serializing via 'meta' attribute on an object
- ENH: supporting a data versioning scheme, warns if this is non-existant or old (only if trying a query)
           as soon as the data is written again, this won't be warned again
- BUG: ixed PyTables version checking (and now correctly raises the error msg)
- BUG/DOC: added min_itemsize for strings in the values block (added TST and BUG fixes)
- BUG: handle int/float in indexes in the Term specification correctly
- ENH/DOC: allow changing of the table indexing scheme by calling create_table_index with new parameters

turned off memory testing: enable big_table test to turn it on
