PURPOSE ^

SYNOPSIS ^

function newstruct = ensemble_tree2datastruct(generic_struct,params)

DESCRIPTION ^


 converts a generic data structure to conform to the ensemble data
 structure

 params struct isn't used yet. This might be useful for specifying
 the type and names fields of the data struct but
