GAMS Transfer Matlab v0.5.0

• Breaking: Changed default Symbol.domain_labels: If Symbol.domain_names is a unqiue list of
  domain names, then those names are used as domain labels. Otherwise, the previous label strategy
  "_" is used. For example, a symbol with domain {i, j}, now expects domain labels i
  and j in records and with a domain {i, j, i} it stays i_1, j_2, i_3.
• Added possibility to modify Symbol.domain_labels to any unqiue list of domain labels. If
  Symbol.domain is modified, domain labels are reset to default label strategy, described above.
• Changed Symbol.domain_forwarding to be a vector of length Symbol.dimension to enable/disable
  domain forwarding for each dimension independently.
• Removed Symbol.getCardinality, Symbol.getUELLabels, Symbol.initUELs and
  Container.getUniverseSet.
• Fixed possibly incorrect order of UELs of symbols in dense_matrix or sparse_matrix format.
• Fixed Symbol.setRecords for cell input and symbols of dimension >= 3.
