anchor.diff:  Introducing BlastWrapper
   ========================
   
  -BlastWrapper is a tool for performing different tasks and in NCBI BLAST console applications (version 2.2.31+).
  -It is able to create BLAST databases and perform blastN or blastP algorithms, while providing a way to set
  -any output parameter for creating a custom output format.
  -Official documentation for all BLAST applications can be found [here] (http://www.ncbi.nlm.nih.gov/books/NBK279690).

   For the purpose of this tutorial, we will build a protein database using a `.fastA` file containing chloroplast proteins
   of Chlamydomonas reinhardtii included in BioFSharp/docs/content/data. 
  
positive.code: (**
  This creates 3 new files in our directory:
  `Chlamy_Cp.fastA.phr`,`Chlamy_Cp.fastA.pin` and `Chlamy_Cp.fastA.psq`.
  We have sucesssfully created our search database.
  
  
  Creating a `.fastA` file from an aminoacid string
  -------------------------------------------------
  
  _Note: this step is not necessary if you want to use an already existing file as query. If this is the case, skip to step 3._
  
negative.code: ---------------------------
  
  We have created our search database and the query we want to find. Before we can perform the actual search, we need to define the BLAST prameters.
  
  _Note: custom output formats can only be specified for output types `CSV`, `tabular` and `tabular with comments`. For more information, check 
  the [options for the command-line applicaions](http://www.ncbi.nlm.nih.gov/books/NBK279675/)_
  
  
  First, lets specify the overall output type. This will define the outline of our output. We want our output to be in tabular form, with added information
  in the form of comments.
  
  _Note: when not specified otherwise, the output type will be `pairwise`_
