```
  Like cook(Scanner), but cooks a set of scripts into one class. Notice that if any of the scripts causes trouble, the entire compilation will fail. If you need to report which of the scripts causes the exception, you may want to use the optionalFileName argument of Scanner(String, Reader) to distinguish between the individual token sources.
  On a 2 GHz Intel Pentium Core Duo under Windows XP with an IBM 1.4.2 JDK, compiling 10000 expressions "a + b" (integer) takes about 4 seconds and 56 MB of main memory. The generated class file is 639203 bytes large.
  The number and the complexity of the scripts is restricted by the Limitations of the Java Virtual Machine, where the most limiting factor is the 64K entries limit of the constant pool. Since every method with a distinct name requires one entry there, you can define at best 32K (very simple) scripts. If and only if the number of scanners is one, then that single script may contain leading IMPORT directives.
  
  Throws:
  
  java.lang.IllegalStateException - Any of the preceeding set...() had an array size different from that of scanners

  On a 2 GHz Intel Pentium Core Duo under Windows XP with an IBM 1.4.2 JDK, compiling 10000 expressions "a + b" (integer) takes about 4 seconds and 56 MB of main memory. The generated class file is 639203 bytes large.
  The number and the complexity of the scripts is restricted by the Limitations of the Java Virtual Machine, where the most limiting factor is the 64K entries limit of the constant pool. Since every method with a distinct name requires one entry there, you can define at best 32K (very simple) scripts.

  Description copied from interface: IScriptEvaluator
  If the parameter and return types of the expression are known at compile time, then a "fast" script evaluator can be instantiated through this method.
  Script evaluation is faster than through IScriptEvaluator.evaluate(Object[]), because it is not done through reflection but through direct method invocation.
  Example:
```
 public interface Foo {
     int bar(int a, int b);
 }
 ...
 IScriptEvaluator se = CompilerFactoryFactory.getDefaultCompilerFactory().newScriptEvaluator();

 // Optionally configure the SE her:
 se.setClassName("Bar");
 se.setDefaultImports(new String[] { "java.util.*" });
 se.setExtendedClass(SomeOtherClass.class);
 se.setParentClassLoader(someClassLoader);

 Foo f = (Foo) se.createFastScriptEvaluator(
     "return a - b;",
     Foo.class,
     new String[] { "a", "b" }
 );
 System.out.println("1 - 2 = " + f.bar(1, 2));
 
```
  All other configuration (implemented type, static method, return type, method name, parameter names and types, thrown exceptions) are predetermined by the interfaceToImplement. Notice: The interfaceToImplement must either be declared public, or with package scope in the same package as the generated class (see IClassBodyEvaluator.setClassName(String)).
  Specified by:
  
  createFastEvaluator in interface IScriptEvaluator
  
  Parameters:
  
  reader - Produces the stream of script tokens
  
  interfaceToImplement - Must declare exactly one method
  
  parameterNames - The names of the parameters of that method
  
  Returns:
  
  An object that implements the given interface

  CompileException
  
  java.io.IOException

```
  Guess the names of the parameters used in the given expression. The strategy is to look at all "ambiguous names" in the expression (e.g. in "a.b.c.d()", the ambiguous name is "a.b.c"), and then at the components of the ambiguous name.
  - If any component starts with an upper-case letter, then ambiguous name is assumed to be a type name.
  - Otherwise, if the first component of the ambiguous name matches the name of a previously defined local variable, then the first component of the ambiguous name is assumed to be a local variable name. (Notice that this strategy does not consider that the scope of a local variable declaration may end before the end of the script.)
  - Otherwise, the first component of the ambiguous name is assumed to be a parameter name.
