MERGE_TDMS - Merges two document collections
    [A, DICTIONARY]=MERGE_TDMS(A1, DICTIONARY1, A2, DICTIONARY2] 
    merges the tdms A1 and A2 with corresponding dictionaries 
    DICTIONARY1 and DICTIONARY2. 
    MERGE_TDS(A1, DICTIONARY1, A2, DICTIONARY2, OPTIONS) defines 
    optional parameters: 
        - OPTIONS.min_local_freq: The minimum local frequency for 
          a term (default 1)
        - OPTIONS.max_local_freq: The maximum local frequency for 
          a term (default inf)
        - OPTIONS.min_global_freq: The minimum global frequency 
          for a term (default 1)
        - OPTIONS.max_global_freq: The maximum global frequency 
          for a term (default inf)
        - OPTIONS.local_weight: The local term weighting function 
          (default 't'). Possible values (see [1, 2]): 
                't': Term Frequency
                'b': Binary
                'l': Logarithmic
                'a': Alternate Log
                'n': Augmented Normalized Term Frequency
        - OPTIONS.global_weight: The global term weighting function 
          (default 'x'). Possible values (see [1, 2]): 
                'x': None
                'e': Entropy
                'f': Inverse Document Frequency (IDF)
                'g': GfIdf
                'n': Normal
                'p': Probabilistic Inverse
        - OPTIONS.normalization: Indicates if we normalize the 
          document vectors (default 'x'). Possible values:
                'x': None
                'c': Cosine
