=============
UPGRADE URGENCY: HIGH, the curve parameters extraction and clustering have been improved
FEATURES:
* dphenome start: slight changes to parameters calculation
* the smoothing algorithm is now less aggressive
* the recursive attempts on curve parameters estimation are reduced two
* dphenome start: clustering improvements
* the curve parameters are normalized prior to clusterization, in order to give all the parameters the same weight
* added a new option (-n) to set the number of clusters (and therefore tha maximum AV)
BUGFIXES:
* dape start: give the right number of distinct reaction IDs in the metabolic network tables
* Other small bugfixes and speed improvements
