Block Modifications:

 digital.mpsk_receiver_cc: Set reasonable default parameter values for GRC definition
 digital.ofdm_insert_preamble: Expose enter_preamble() as public, to allow external state changes
                               Cleanup of incorrect forecast behavior
                               Make the flag port optional, incase external preamble triggers are preferred to in-band
 gr_vector_source: added set_data( data ) and rewind() public methods
 gr_head: added set_length(int) method to modify head length

New Blocks Added:
 gr_keep_m_in_n: Allows periodic extraction of M items instead of 1 (in keep_1_in_n)
 gr_pack_k_bits: Complementary block fo gr_unpack_k_bits
 gr_vector_insert_x: Complement to the gr_head block, inserts a vector into a stream then becomes a pass through
