/**
* Marker annotation
* that indicates that the annotated method or field is to be ignored by
* introspection-based
* serialization and deserialization functionality. That is, it should
* not be consider a "getter", "setter" or "creator".
*
* For example,
* a "getter" method that would otherwise denote
* a property (like, say, "getValue" to suggest property "value")
* to serialize, would be ignored and no such property would
* be output unless another annotation defines alternative method
* to use.
*
* This annotation works purely on method-by-method (or field-by-field) basis;
* annotation on one method or field does not imply ignoring other methods
* or fields.
* Specifically, marking a "setter" candidate does not change handling
* of matching "getter" method (or vice versa).
*
* Annotation is usually used just a like a marker annotation, that
* is, without explicitly defining 'value' argument (which defaults
* to true): but argument can be explicitly defined.
* This can be done to override an existing JsonIgnore by explictly
* defining one with 'false' argument.
*
* Annotation is similar to {@link javax.xml.bind.annotation.XmlTransient}

* For most cases, however, default value of "true" is just fine
* and should be omitted.
