Opc point types

As seen in the opc palette (Figure 11), there are 6 different Opc proxy point types: BooleanPoint, BooleanWritable, NumericPoint, NumericWritable, StringPoint, and StringWritable.

These 6 types are simply a subset of the 8 basic control point types, minus the EnumPoint and EnumWritable. Each point type has an Opc Proxy Ext (proxy extension).
