ValueExtractorA canonical name uniquely identifies what is to be extracted, but not how it is to be extracted. Thus two different extractor implementations with the same non-null canonical name are considered to be equal, and should reflect this in their implementations of hashCode and equals.
Canonical names for properties are designated by their property name in camel case,
for instance a Java Bean with method getFooBar would have a property named fooBar,
and would have fooBar as its canonical name.
Canonical names for zero-arg method invocations are the method name followed by ().
Dots in a canonical name delimit one or more property/method accesses represented by a chaining
ValueExtractor such as ChainedExtractor or
PofExtractor(Class, PofNavigator, String).
There is currently no canonical name format for methods which take parameters and
as such they must return a canonical name of null.

AbstractExtractor.equals(Object) contract takes precedence when applicable,
falling back to implementation specific equals.
Two ReflectionExtractor objects, re1 and re2 are considered equal iff re1.extract(o) equals re2.extract(o) for all values of o.
