Library "WeightedSumIndex"
WeightedSumIndex: Helper class to build indices.
Index value is a normalized weighted sum of all its input signals.
The value is from 0 to 100

fun(x)
  TODO: add function description here
  Parameters:
    x (float): TODO: add parameter x description here
  Returns: TODO: add what function returns

init()
  Initialize an Index
  Returns: A new instance of Index object with no signals

method add(idx, signal)
  Adds the specified signal to the index
  Namespace types: Index
  Parameters:
    idx (Index): The Index object
    signal (Signal): Signal object

method calc(idx)
  Caclulates the Index value
  Namespace types: Index
  Parameters:
    idx (Index): The Index object
  Returns: Normalized weighted sum of all signals with on=true

method update(idx)
  Calculates the Index value by calling idx.calc() and stores its value in the Index object.
  Namespace types: Index
  Parameters:
    idx (Index): The Index object

Signal
