docs: Utility method to set property value of an object by using the dot notation of the affected property
  
  For instance, for the following object:
  var someObject =
  {
  animals: {
  cow: true,
  cat: false
  }
  };
  
  If we want to change the property val of 'cat', we can use this function to do so:
  
  setPropertyVal (someObject, 'animals.cat', true);
  
  @param pObj Object whose property value needs to be updated
  @param pProp dot notation property value, e.g. 'animal.cat'
  @param pNewVal new value with which the property @param pProp will be updated with
