Added the preprocessor symbol to Vector

Controls whether to use expression or dynamic for generic operations
Integrable/PolyFunc and Operations

Added the Operations<T> class to encapsulate the Expressions business
Finished the IntegrableFunction/PolyFunc business, need to add a Bezier

Not to mention a piecewise function for the integrablefunction business,
so we can do the whole time thing which inspired integrable function in
the first place.
Removed ArbitraryRender
