Kmer minhashing in Julia

This package is work in progress. I'll work on it when I have time.

The purpose of this package is to:

• Provide a simple Julia interface
• Provide methods for minhashing DNA sequences and FASTA files
• Provide methods for distance calculation between minhash sketches
• Be highly efficient

The purpose of this package is NOT:

• To hash amino acids or arbitrary alphabets
• To hash reads. This functionality may be added later.

Note: The API is not stable. Version is not yet 1.0

To be determined.

Case 1: Sketching 1 core, 51k sequences, 330 Mbp, 1 sketch
