public interface VariableNameChecker

This interface defines the methods for a class that checks characters to determine whether they're legal for a variable name that's to be substituted by a VariableSubstituter object. It has a single method, legalVariableCharacter(char), which determines whether a specified character is a legal part of a variable name or not. This capability provides additional flexibility by allowing callers to define precisely what characters constitute legal variable names.
