REVISION HISTORY
Description: Put declaration of getfill in this file.
Description: Remove prstflag from get_ics_info declaration.
Description: Trivial change of the data type of one of the parameters to
get_ics_info.
Description: Change where get_ics_info is declared.
Description: Clean up comments
Description: (1) Add declaration of binary tree search function for Huffman
decoding
(2) #if the traditional and optimized linear seach methods.
Description: Modified per review comments
(1) delete #if traditional and optimized linear seach methods
Description: Merged Ken's change on getics: delete pFrameInfo from argument
list
Description: Added function definition for table specific huffman decoding
functions.
