track.CNV.DGVsupp: DGV supporting variant parser
In cghRA: Array CGH Data Analysis and Visualization

This function constructs track.CNV objects from free annotation files provided by the Database of Genomic Variants.

It is designed to parse supporting variants, as opposed to track.CNV.DGV provided by Rgb which is designed to parse DGV Variants.

1	track.CNV.DGVsupp(file, name = "DGV CNV (supporting variants)", quiet = FALSE, ...)

`file`	Single character value, the path to the raw file to parse. See the 'References' section below.
`name`	Single character value, the `name` field for the `track.table` object.
`quiet`	Single logical value, whether to print diagnostic `message`s or not.
`...`	Further arguments are passed to the class constructor, as a result most of the handled arguments are `track.table` arguments. Consider notably `.organism` and `.assembly` for track annotation.
