[Feature Request]Rework BioCollections

[kMutagene]

BioSeq, BioArray, and BioList have inconsistent function naming and missing functionality:

different functionality:

• (Naming) transcribeCodingStrand/transcribeCodeingStrand (BioSeq/BioArray)
• (function signature) Digestion.[CollectionName].digest

missing functionality:

• conversion the same as standard collections: BioSeq.ofBioArray etc.

• create cDNA from mRNA

• find first start codon

• find gene (first start codon –> first stop codon)

• all functions with the signature kind collection -> .. -> collection need to be abstracted, e.g. BioArray.map

• (Debatable, Breaking): put the types in the toplevel namespace and make the functions static members. Has the advantage of less namespace Clutter (BioFSharp.BioSeq.BioSeq<#IBioItem> becomes BioFSharp.BioSeq<#IBioItem>)
