Detailed Description

Generates dummy random data, just for testing the "learning" code.

Arguments:

1. nb of inputs (default is DEF_NB_INPUTS)
2. nb of points (default is DEF_NB_POINTS)

This app:

1. creates a FIS
2. generates some synthetic data
3. generates FIS rules using the synthetic data
4. reduces the rule base
5. saves the rule base into two files: "rulebase_nosort.csv" and "rulebase_sort.csv"

Step 1 : setting up a fis with the correct nb of inputs and without any rules

Step 2 : generating random data points, creating a rule for each point vector, and creating the data file
