...com/BHoM/Revit_Toolkit into Revit_Toolkit-#1444-FilterPrototype

To simplify the mirroring representation of the Revit API classes within the BHoM, it's necessary to add a concrete classe, subclass of FilterRule, that
corresponds to the FilterValueRule from Revit API.
Whatever sub-class type as well as Evaluator class type will be represented in BHoM via enumeration classes assigned to the RevitFilterRule and RevitFilterValueRule
as attributes.

Instead of using a single class FilterRule with an Enumeration encapsulated to represent all the different Revit API Filter Rules,
we go for creating multiple classes and sub-classes in BHoM as well, thus trying to match as much as possible the classes structure
that is present in the API.

Add NOT_START_WITH and NOT_ENDS_WITH enum values to the enumeration.
These are required to implement the View Filtering in BHoM.

Instead of keeping the conversion of FilterRule objects from/to Revit/BHoM within the ParameterFilter/ViewFilter
conversion classes only, we split the code in each different FilterRule Class keeping the code more modular and reusable.

The View3D Class is a subclass of the View Class. To let the BHoM run the Update method on the View3D class, we need to specify an overloaded version of the Update Method taking a View3D class instance rather than a View class instance as input.

...neric Type
Since View3D is a subclass of View in the Revit API, we can make the Update method work on a generic type T, specifying that it must be extending the revit api superclass View.

Using this abstract class it's possible to decouple the ParameterValuePresence Class from the FilterValueRule class.
