  * edoSamplerUniform
  * This class uses the Uniform distribution parameters (bounds) to return
  * a random position used for population sampling.
+ *
+ * Returns a random number in [min,max[ for each variable defined by the given
+ * distribution.
+ *
+ * Note: if the distribution given at call defines a min==max for one of the
+ * variable, the result will be the same number.
