Generates a hybrid search function based on Linear Consistency-Constrained algorithm described in \insertCiteShinXu2009FSinR. The algorithm combines two evaluation measures, the first evaluates each feature individually, and the second measure evaluate feature sets.

## The direct application of this function is an advanced use that consists of using this
# function directly and performing a hybrid search process in a feature space
## Classification problem
# Generates the first filter evaluation function (individual or set measure)
filter_evaluator_1 <- filterEvaluator('determinationCoefficient')
# Generates the second filter evaluation function (mandatory set measure)
filter_evaluator_2 <- filterEvaluator('ReliefFeatureSetMeasure')
# Generates the hybrid search function with LCC
LCC_hybrid_search <- LCC()
# Run the search process directly (params: dataset, target variable, evaluator1 & evaluator2)
