funBI_harvesting: funBI Harvesting
In JacopoDior/funBI: a Biclustering Algorithm for Functional Data

Perform Harvesting to a list of DIANA hierarcy obetained using the funBI_lot_and_flower function. The available harvesting strategies are three: a delta-threshold strategy, a dynamic strategy with a threshold obtained as a percentage of the total hscore of a considered hierarchical dendrogram, and an automatic strategy using gap statistics.

1	funBI_harvesting(list_hc, delta, perc, gap, mat, Kmax, B)

`list_hc`	a list of hierarchy resulting from DIANA built from `mat`
`delta`	a scalar value indicating the delta-threshold in order to perform a delta-bicluster. In this case `perc` and `gap` should be missing.
`perc`	a scalar value indicated a percentage of the total score in order to perform a delta-bicluster cut using as delta-threshold the percentage `perc` of the total hscore of a particular dendrogram. In this case `delta` and `gap` should be missing.
`gap`	TRUE/FALSE indicating if gap statistics should be used as Harvesting strategy.In this case `delta` and `perc` should be missing.
`mat`	a matrix
`Kmax`	the maximum number of clusters to consider when performing gap statistics (`gap` = TRUE), must be at least two.
`B`	integer value, number of Monte Carlo (“bootstrap”) samples to consider when performing gap statistics (`gap` = TRUE).

biclist, a list containing all the candidate biclusters according to the used Harvesting strategy. Every element of the list is a bicluster. Every bicluster is characterized by the following components:

a vector containing the elements belonging to the bicluster reprented using the row index/label of the matrix mat
a vector containing the boundaries of the sub-interval considered represented usign the colum index/label of the matrix mat
the Hscore of the bicluster
The index of list_hc, representing which dendogram the bicluster was cut
