	bootstrap-extensions/src/main/java/de/agilecoders/wicket/extensions/markup/html/bootstrap/form/spinner/SpinnerConfig.java
added sample
Merge branch 'master' of https://github.com/danjee/wicket-bootstrap.git
Added improved javadoc
Added chained constructors
Added default values in configuration
Also an ugly workaround in default keys max, min and step

I think a modification has to be made in jquery-selector AbstractConfig
so the use of 

private static final IKey<? extends Number> max = newKey("max",100);

will be valid
remove white lines
import resources with eclipse 'Save actions' disabled
remove whitespaces
Format markup
use getConfig() instead of config object
use getConfig() instead of config object
add default values
Merge branch 'master' of https://github.com/danjee/wicket-bootstrap
