/**
 * Knows how to convert Booleans.  This is only required because of the Java's
 * funky incoherence of primitive types vs wrapper types - when you have a primitive
 * type field, the value will be Boolean.class but the fieldType will be Boolean.TYPE.
 * The normal assignableTo test will fail and we'll go through the converters.  This
 * converter is just smart enough to recognize Boolean.TYPE and continue on as normal
 * for the (expected) wrapper type.
