Class Description

 WaveRDC class is the class for compressed data
 structures and methods.

 Default constructor

 Destructor

 Lists layers stored in compressed array,
 "v" - is verbosity level, =0 by default.

 Resizes dataz array of object to new length NZ = n.

 Dumps dataz array to file *fname in binary format and type "short".
 Variable 'app' select write mode, app=0 - write new file,
 app=1 - append to existent file.

 Compress packs data into layer which is series of blocks each
 consisting of bricks of two different length 'kl' and 'ks'. Each
 brick represents one element of original unpacked data
 (16-bit integer) which is shortened to exclude redundant bits.
 Original data are taken from object wd. Packed data are
 placed into array 'dataz'. Returns number of bytes
 occupied by compressed data.

 Push takes unsigned int u  and packs it as a word k-bit leng
 into the compressed data array "cd".
 ncd counts the # of unsigned int words filled with compressed data.

 Unpacks data from the layer 'm' which is series of blocks each
 consisting from bricks of two different length 'zl' and 'zs'.
 Each brick represents one element of original unpacked data
 (16-bit integer) which is shortened to exclude redundant bits.
 Returns number of bytes occupied by unpacked data.

 Pop unpacks one element of dataz. ncd - current position in the array
 freebits - number of unpacked bits in dataz[ncd]

 Pop unpacks "n" elements of data which are stored in compressed
 array "dataz" as a series of "n" words of k-bit length. Puts
 unpacked data to integer array "dt" and returns number of words decoded

 Stream a WaveRDC object. Required by ROOT system for
 reading and writing the object to file.
