<init>

Searches the attribute subset space by forward selection.

search

Records whether the user has requested a ranked list of attributes.

setGenerateRanking

Set whether to search backwards instead of forwards

setSearchBackwards

converts a BitSet into a list of attribute indexes

attributeList

determineNumToSelectFromThreshold

Gets whether conservative selection has been enabled

getConservativeForwardSelection

Get whether to output debugging info to the console

getDebuggingOutput

Gets whether ranking has been requested. This is used by the AttributeSelection
module to determine 

getGenerateRanking

getNumExecutionSlots

Gets the number of attributes to be retained.

getNumToSelect

getSearchBackwards

Returns a list of attributes (and or attribute ranges) as a String

getStartSet

Returns the threshold so that the AttributeSelection module can discard
attributes from the ranking.

getThreshold

numExecutionSlotsTipText

resetOptions

Set whether attributes should continue to be added during a forward search as
long as merit does not

setConservativeForwardSelection

Set whether to output debugging info to the console

setNumExecutionSlots

Specify the number of attributes to select from the ranked list (if generating a
ranking). -1 indica
