Default Schema for reading a text delimited org.apache.mahout.math.indexeddataset.IndexedDataset file where the score of any element is ignored. This tells the reader to input DRM lines of the form (rowID<tab>columnID1:score1<space>columnID2:score2...) remember the score is ignored. Alternatively the format can be (rowID<tab>columnID1<space>columnID2 ...) where presence indicates a score of 1. This is the default output format for IndexedDatasetWriteBooleanSchema
