Add gh-pages documentation for BioFSharp.Mz

[caroott]

This branch adds a documentation site for BioFSharp.Mz and BioFSharp.Mz.Vis, built with fsdocs and styled like the BioFSharp site.

Pages

Ten .fsx pages under docs/, grouped into four categories:

Spectrum processing

• 01_01_peaks_and_peak_arrays: the Peak and PeakArray types, reading an MGF spectrum, centroided peak data.
• 01_02_signal_detection: wavelet peak picking with padding, the parameters that drive it, and the peaks it produces from a raw MS1 scan.
• 01_03_charge_state_determination: isotope cluster detection and charge inference, including the significance test behind the reported scores.

Peptide identification

• 02_01_fragmentation: in silico b and y ion series with neutral losses, matched against a real MS2 spectrum.
• 02_02_search_databases: building and querying the SQLite peptide database from a FASTA file with a tryptic digest and a mass window.
• 02_03_sequest_like_scoring: the xcorr score computed for candidate peptides.
• 02_04_andromeda_like_scoring: the binomial Andromeda score and the X!Tandem hyperscore side by side.

Quantification

• 03_01_quantification: extracted ion chromatograms, start-parameter estimation and Gaussian or EMG peak fits.

Validation and inference

• 04_01_fdr_control: target-decoy FDR, q-values, posterior error probabilities.
• 04_02_protein_inference: peptide-to-protein evidence classes and the two inference modes.

Every code block runs against the built assemblies, and every output block on a page is the verbatim output of that run. The pages use the small data files in docs/data/ (two MGF spectra and a Chlamydomonas chloroplast FASTA).

Site

• docs/index.md introduces the library and links the categories.
• docs/_head.html and docs/img/favicon.ico match the BioFSharp look.
• build/DocumentationTasks.fs builds the site with https://biofsharp.com/BioFSharp.Mz/ as root.
• Binder, script and notebook badges follow the same layout as the BioFSharp pages.
