  * No longer uses index pairs
  * Now called `snapshot`
* New `prism` function
* New `bucket` function
* New `mds` function
* New vignette

## propr 2.0.1
---------------------
* Modified `phit`, `perb` functions
  * These functions now force zero removal
* New `simplify` function
  * Subsets `propr` object based on index in `@pairs` slot

  * Added `lazyPairs` construct
    * Slot @pairs not populated until after `[`
* Modified `propr` Class
  * `@pairs` slot now integer vector
    * Populated with `indexPairs` function
      * Translate with `indexToCoord` function
  * `show` method updated for `lazyPairs` construct
  * `[` method completely redesigned
    * First argument specifies operation
    * Second argument specifies reference
    * Indexes @matrix based on these
  * `subset` method revised but still copy-on-modify
    * Resets @pairs when called
  * `$` method removed
* Visualization tools revised
  * `plot`, `image`, `dendrogram` methods
    * Improved performance
    * Compatible with new @pairs indexing
    * No longer requires column names

  * Rephrased code for `proprVLR`
  * All functions translated into C++
    * Estimated 80% reduction in RAM overhead
    * Estimated 100-fold performance increase
    * ALR methods no longer drop dimension
    * All have modify-in-place behavior
