/**
* Locates all classes with certain capabilities. One should keep in mind,
* that works only with the default capabilities of a scheme and doesn't
* take dependencies into account. E.g., a meta-classifier that could have
* a base classifier handling numeric classes, but by default uses one with
* a nominal class, will never show up in a search for schemes that handle
* numeric classes.
*
* Valid options are:
*
* All class and attribute options can be prefixed with 'not',
* e.g., '-not-numeric-class'. This makes sure that the returned
* schemes 'cannot' handle numeric classes.
*
*
* -num-instances <num>
* The minimum number of instances (default 1).
*
* -unary-class
* Must handle unray classes.
*
* -binary-class
* Must handle binary classes.
*
* -nominal-class
* Must handle nominal classes.
*
* -numeric-class
* Must handle numeric classes.
*
* -string-class
* Must handle string classes.
*
* -date-class
* Must handle date classes.
*
* -relational-class
* Must handle relational classes.
*
* -missing-class-values
* Must handle missing class values.
*
* -no-class
* Doesn't need a class.
*
* -unary-atts
* Must handle unary attributes.
*
* -binary-atts
* Must handle binary attributes.
*
* -nominal-atts
* Must handle nominal attributes.
*
* -numeric-atts
* Must handle numeric attributes.
*
* -string-atts
* Must handle string attributes.
*
* -date-atts
* Must handle date attributes.
*
* -relational-atts
* Must handle relational attributes.
*
* -missing-att-values
* Must handle missing attribute values.
*
* -only-multiinstance
* Must handle multi-instance data.
*
* -W <classname>
* The Capabilities handler to base the handling on.
* The other parameters can be used to override the ones
* determined from the handler. Additional parameters for
* handler can be passed on after the '--'.
* Either '-W' or '-t' can be used.
*
* -t <file>
* The dataset to base the capabilities on.
* The other parameters can be used to override the ones
* determined from the handler.
* Either '-t' or '-W' can be used.
*
* -c <num>
* The index of the class attribute, -1 for none.
* 'first' and 'last' are also valid.
* Only in conjunction with option '-t'.
*
* -superclass
* Superclass to look for in the packages.
*
*
* -packages
* Comma-separated list of packages to search in.
*
* -generic
* Retrieves the package list from the GenericPropertiesCreator
* for the given superclass. (overrides -packages <list>).
*
* -misses
* Also prints the classname that didn't match the criteria.
