• Added possibility to change symbol name case with Container.renameSymbol.
• Added possibility to reorder UELs by record order with Symbol.reorderUELs (passing no
  arguments).
• Added Container.getSets, Container.getParameters, Container.getVariables,
  Container.getEquations and Container.getAliases to get list of symbol objects of corresponding
  type.
• Added possibility to get/remove all symbols with Container.getSymbols or
  Container.removeSymbols, respectively.
• Added Container.lowerUELs, Container.upperUELs, Symbol.lowerUELs and Symbol.upperUELs to
  convert (all) UELs to lower or upper case, respectively.
• Added GDX library unload before each read/write operation.
• Added columns where_min and where_max to output of Container.describeParameters.
• Changed used GDX library to gdxcclib64.
• Changed column names in output of Container.describe* methods: dim -> dimension, num_recs
  -> number_records, num_vals -> number_values, min_value -> min, max_value -> max,
  mean_value -> mean.
• Removed *_marginal, count_*, where_max_abs_value and is_alias columns in output of
  Container.describe* methods.
• Removed ConstContainer.
• Fixed bug that limited the number of used UELs in Symbol.transformRecords and Symbol.getUELs.
• Fixed Container.eq in case of containers with different number of symbols.
