q-beanutils

Jakarta commons-beanutils PropertyUtils replacement.

Install:

<dependency>
        <groupId>eu.qualityontime.commons</groupId>
        <artifactId>q-beanutils</artifactId>
        <version>0.8</version>
</dependency>

Plan:

1. [Done] Wrap of Jakarta commons PropertyUtils to avoid checked excecptions and adding some generics friendly method.
2. [Done] Take over jakarta commons implementation and eliminate the use of DynaBeans.
3. [Prog]Add field access by the @ notation. Example: attr1.@field1
   1. [Done]set and get field
   2. copy properties map to field
   3. copy properties obj from field/attr to field/attr
4. Make it working with non public beans.
5. [Done] Add null attribute access. Example: attr1?.attr2
6. Add collection accessors. Example. Taken attr1 as a List expression attr1*.attr2 gets all the attr2 values in collection. See Groovy spread operator. (http://docs.groovy-lang.org/latest/html/documentation/#_spread_operator)

Nullable attribute access has a limitation.
When the attribute is accesse like getIndexedProp(int index) then the underlying method must take care of nullability.

As QPropertyUtils is behaving like commona PropertyUtils most behaviours are the same (http://commons.apache.org/proper/commons-beanutils/javadocs/v1.9.3/apidocs/org/apache/commons/beanutils/package-summary.html)
