VarTypeVoteBase	Abstract base class that represents a vote for the type of a variable.
VarTypeVotePeekData	Represents a vote for type of a variable where the type or value of data (e.g., column) from a report or result must be "peeked at" to properly determine the type of the target variable.
VarTypeVotePeekVariable	Represents a vote for type of a variable where the type or value of another variable (or variables, for example, a binary operation) must be "peeked at" to properly determine the type of the target variable.
VarTypeVoteStatic	Represents a vote for type of a variable where all information is available at compile-time, i.e., just from parsing a RUN command.
