Detailed Description

The general scheme of implementing a PicHunter like algorithm in GIFT uses the following scheme:

If you want a suggestion of n< > elements get 2n< > elements. Call them the s_i.

For the same dbSize/10 (or something) elements (which we will call the e_i) calculate the distance (s_i,d_j) for all i and j possible. (Leading to something like 500 comparisons in our case).

For each s_i the delta_{ij} will be stored in a structure of the type CComparisonResults
