EvaluatorBase currently provides CompileMethod() and CompileCode(), but no CompileFile(). However:

• The class provides CompileAssemblyFromCode() and CompileAssemblyFromFile().
• The class' protected Compile method provides both parameters:
  Compile(string scriptText, string scriptFile, CompileInfo info)

To me, this interface is a bit inconsistent and I would prefer a CompileFile() method over having to call CompileCode(File.ReadAllText(scriptFile).

Goodie:
EvaluatorBase Line #777 and EvaluatorBase Line #827 could then also use CompileFile() rather than having to duplicate File.ReadAllText(scriptFile).
