Class NetNode

Given a set of inputs (valVect), returns the output of this node

**Arguments**

 - valVect: a list of inputs

**Returns**

   the result of running the values in valVect through this node

Sets the input list

**Arguments**

  - inputNodes: a list of _NetNode_s which are to be used as inputs

**Note**

  If this _NetNode_ already has weights set and _inputNodes_ is a different length,
  this will bomb out with an assertion.
  

Sets the weight list

**Arguments**

  - weights: a list of values which are to be used as weights

**Note**

  If this _NetNode_ already has _inputNodes_  and _weights_ is a different length,
  this will bomb out with an assertion.
  

Constructor

**Arguments**

  - nodeIndex: the integer index of this node in _nodeList_

  - nodeList: the list of other _NetNodes_ already in the network

  - inputNodes: a list of this node's inputs

  - weights: a list of this node's weights

  - actFunc: the activation function to be used here.  Must support the API
      of _ActFuncs.ActFunc_.

  - actFuncParms: a tuple of extra arguments to be passed to the activation function
      constructor.

**Note**
  There should be only one copy of _inputNodes_, every _NetNode_ just has a pointer
  to it so that changes made at one node propagate automatically to the others.
