To execute complete divisive hierarchical clusterization algorithm by choosing distance and approach types.

1	divisiveHC(data, distance, approach)

`data`	could be a numeric vector, a matrix or a numeric data frame. It will be transformed into matrix and list to be used.
`distance`	is a string. It chooses the distance to use.
`approach`	is a string. It chooses the approach to use.

This function is the main part of the divisive hierarchical clusterization method. It executes the theoretical algorithm step by step.

1 - The function transforms data in useful object to be used.

2 - It creates a cluster that includes every simple elements.

3 - It initializes posible clusters using the initial elements.

4 - It calculates a matrix distance with the clusters created in the 3rd step.

5 - It chooses the maximal distance value and gets the clusters to be divided.

6 - It divides the cluster into two new complementary clusters and updates the clusters list.

6 - It repeats these steps until every cluster can't be divided again. The solution includes every simple cluster.

A list with the divided clusters.
