ComputeMAP/ComputeMAP.cpp
* Printed to standard output status messages to see the Average Precision used to compute mAP and in turn the precision and recall used to compute that.
* Added the feature of saving precision and recall for each query at different number of candidates, useful for example to compute the ROC curve.

ComputeMAP/Makefile
* Separated compilation from linking and added a preprocessor directive to control the printing of status messages to standard output.

scripts/eval_performance.m
scripts/plot_performance_rates.m
scripts/script_eval_performance.sh
* Implemented scripts for printing ROC curve for the different precision and recall values of each query.
