SYNOPSIS ^

function as = init_analysis_struct()

DESCRIPTION ^

 Initializes an analysis structure for pulling data out of the mysql database

 as = init_analysis_struct()

 There are two basic sub-structures within an analysis structure. 
 1) The .num structure contains numeric responses to questions. Most

 2) The .txt structure contains text responses

 Both of these structures include additional fields with information for
 decoding the .data matrices.
