[VWMA] Net Volume Library

Library " Net Volume Library"
TODO: The underlying logic and function that calculates the net volume for the Net Volume indicator. Exposes the nv function and nvPoint fields for use.

nv(src, length, useVwma, offset, sigma, multHigh, multMed, multLow)
  Parameters:
    src: (float) The source price value
    length: (int) The lookback length
    useVwma: (bool) To use VWMA in the calculation or not
    offset: (float) The ALMA offset value
    sigma: (int) The ALMA sigma value
    multHigh: (float) The multiplier high band
    multMed: (float) The multiplier medium band
    multLow: (float) The multiplier low band
  Returns: Returns the calculated net volume for each band in an nvPoint object

nvPoint
  Fields:
    h2
    h1
    h
    n
    l
    l1
    l2

• Exposed getBandColor to allow same band coloring as Indicator
  
• Added nvPoint type documentation
  

Added:
getBandColor(value, transp, negative, positive)
  Gets the band color based on a positive or negative alma value
  Parameters:
    value: (float) The value to pass in to check against
    transp: (int) The transparency value. Ex: 0 = solid, 100 = fully opaque
    negative: (color) The color to show when result is below but not equal to 0
    positive: (color) The color to show when result is above but not equal to 0
  Returns: (color) The color that matches the result of being above or below 0

Updated:
nvPoint
  Contains 7 bands of net volume data points
  Fields:
