distops 0.1.0

Features

• Provides functions use_distops() and use_distance() for package developers to define TBB-parallelized functions to compute pairwise distance matrices using a custom C++-implemented distance function.
• Provides subset operator [.dist to subset a distance matrix. The returned object is either of class dist if both row and column indices are identical or of class matrix if both row and column indices are different.
• Provides function find_medoids(D, memberships = NULL) to find medoid(s) of a distance matrix. If memberships is provided, one medoid per cluster is returned. Otherwise, a single overall medoid is returned.
