A description of how to protect a method from reentry.

A value of true is transformed using the key as the all value. For example, this:

 class Foo extends Base.mixin(Fencible) {
     static fenced = {
         foo : true
     };

Is equivalent to this:

 class Foo extends Base.mixin(Fencible) {
     static fenced = {
         foo : {
             all : ['foo']
         }
     };

Strings are split on spaces to produce the all array. For example, this:

 class Foo extends Base.mixin(Fencible) {
     static fenced = {
         foo : 'foo bar'
     };

Is equivalent to this:

 class Foo extends Base.mixin(Fencible) {
     static fenced = {
         foo : {
             all : ['foo', 'bar']
         }
     };

This indicates that foo() cannot be reentered if foo() or bar() are already executing. On entry to foo(), both foo() and bar() will be fenced (prevented from entering).
