This function removes from the database the variant locations labelled as over-conflicting by the PCC.overconflicting function.

1	PCC.elimination(x)

`x`	an object of class pccOverconflicting.

When PCC.overconflicting has been applied to a PCC.conflicts object, it returns a table where over-conflicting variants are labeled as such. The PCC.elimination function simply removes those variants.

A numeric matrix, with witnesses in columns, variant locations in rows, and readings coded by a number, from which over-conflicting variant locations have been removed.

The notion of using a centrality threshold for the identification of over-conflicting variant locations is found in Camps & Cafiero 2015. Other formulas for this centrality might be implemented in the future.
