Added extract_weight(string featureVectors)::weights UDF
Modified to reuse a decompressor
Fixed a bug and supported a new function signature:
distcache_gets(const string FILEPATH, object[] key, object[]
defaultValues)::map<key_type, value_type>
Added "-outputs_touched" option.
If the option is specified, outputs weights touched in training.
This option is intended to use with "-loadmodel" option.
