Prepare CRAN release

[wleoncio]

• [x] Internalize functions other than greedyMix()
• [x] Stop to-be-implemented functions on greedyMix()
• [x] Add examples to greedyMix()
• [x] Incorporate functions that performs clustering on greedyMix()
• [x] Achieve minimal input of greedyMix()
• [x] Achieve minimal input of greedyMix() with indMix() parsing
• [ ] Make sure output of greedyMix() for FASTA files is correct (minimum quality for CRAN release)
• [ ] Decide package function (rBAPS or BAPS?)
• [ ] Create GH issue form for easy reporting
• [ ] Add welcome message on load with URL to issues

Some ideas/insights after a meeting with Jukka:

• [x] Fasta dataset: generate more data
  • Replicate the dataset 10-20x for each individual (row)
  • Generate more columns (ACGT alphabet)
• [ ] Set cluster default to 5 (all dimensions of all generic objects?)
  • Alternatively, re-dim used generics before handling them
• [x] Investigate df_fasta$data
  • ~It has 6 rows when it should have 5~ (looks like MATLAB also does that)
  • ~The first row is just zeros: may be an error~ (handleData() adds a row of zeros, even on MATLAB)
  • ~Why 99 columns when each individual has 100 letters?~ (handleData() drops column with 1 unique letter)
• [ ] Investigate ninds calculation
  • Perhaps indMix() gets stuck because ninds is at 2 (when there are 5 individuals)
  • A higher ninds, say 5, should help
• [x] Create new haploid data from BAPS_format_clustering_diploid.txt (are BAPS files going to be supported? No pre-processing available (importFile(), handleData())
  • Each individual (integer in last column) has two rows assigned to them (ergo, "diploid")
  • Some creatures have 4 rows (tetraploid)
  • Erase every other row to create a sinthetic haploid example
