/** These macros define the following functions, necessary but repetitive for
 * every Action:
 *  -# Dialog* fillDialog()
 *  -# action command (e.g. AnalysisMolecularVolume() )
 *  -# void getParametersfromValuStorage()
 *  -# struct Action...Parameters
 *
 *  For this, the user has the define the following values, each with
 *  parenthesis, for the values/parameters the action needs
 *  -# paramtypes, e.g. (int)(double)
 *  -# paramtokens, e.g. ("Z")("length")
 *  -# paramreferences, e.g. (Z)(length)
 *  and for additional values/parameters to save in the state
 *  -# statetypes, e.g. (int)(double)
 *  -# statereferences, e.g. (Z)(length)
 *  and the name and category of the action
 *  -# CATEGORY, e.g. Analysis
 *  -# ACTIONNAME, e.g. MolecularVolume
