    createIfNotExists createIfNotExist (default to: true) do we must create the instance if the instance is not found ?
    withoutSecurity (default to false) must override the security at the creation of the target instance (we use the surfer who is at the origin of the denormalization)
    withoutTriggers (default to false) should we ignore the triggers ?

- class : com.wedia.packaged.dam.triggers.datatransformers.impl.RegExpPatternMatcher
  init : java.lang.String (a regular expression) or an org.json.JSONObjectthat can define :
  - regexp : java.lang.String a regular expression
  - outputNullIfNoMatch : boolean (default false)
  - .matches() is used in the java service, so it is important that the entire input must match the regular expression.
  - The regular expression should be a capturing one with “( )”, and as said before, it should be made for the entire input (by using .*).
    - Example : Regex to match the first 7 characters of your input : "^(.{7}).*"
- init : java.lang.String (a regular expression) or an org.json.JSONObjectthat can define :
  - regexp : java.lang.String a regular expression
  - outputNullIfNoMatch : boolean (default false)
  - outputFirstNotEmptyGroup : boolean (default false)
- input : a transformation returning java.lang.String
- output : Checks the regular expression on the input. Depending on the options :
  - If the regular expression does not matches, returns null if outputNullIfNoMatch is true, returns the input otherwise
  - If the regular expression match
    - returns the value of the first group capturing non null and non empty if outputFirstNotEmptyGroup (group 0 excluded)
    - returns the value of index group 1 otherwise
