## Draw Legend for caOmicsV bioNet Plot

### Description

The bioNet legend includes a heatmap color scale and names for each track, such as "1. Tissue: T(red), N(blue)", "2. Methylation", "3. miRNA hsa-mir-424", "4. Gene Expression", ... A graphic device and igraph object must be initialized first.

### Usage

        bioNetLegend(dataNames, textCoor=NULL, heatmapCoor=NULL,
            scaleWidth, scaleHeight, heatmapMin=-3, heatmapMax=3,
            colorType="BlueWhiteRed", direction="h")

### Arguments

`dataNames` | character vector, names of data on each circular track
`textCoor` | numeric vector of length 2, x and y coordinates for legend text.
`heatmapCoor` | numeric vector of length 2, x and y coordinates for heatmap colour scale
`scaleWidth` | non-negative numeric, length (width) of heatmap color scale
`scaleHeight` | non-negative numeric, height of heatmap color scale
`heatmapMin` | numeric, minimum value of heatmap color scale, default -3 (z-score)
`heatmapMax` | numeric, maximum value of heatmap color scale, default 3 (z-score)
`colorType` | character vector, one of "BlueWhiteRed", "GreenWhiteRed", "GreenYellowRed", "GreenBlackRed" , or "YellowToRed"
`direction` | character, direction of heatmap color scale, either 'h' for horizontal or 'v' for vertical.

### Value
