Windowed Multipole Library Format

The current version of the statepoint file format is 1.1.

/
- Attributes :
  - filetype (char[])
    
    String indicating the type of file.
  - version (int[2])
    
    Major and minor version of the data.
/<nuclide name>/
- Datasets :
  - broaden_poly (int[])
    
    If 1, Doppler broaden curve fit for window with corresponding index. If 0, do not.
  - curvefit (double[][][])
    
    Curve fit coefficients. Indexed by (reaction type, coefficient index, window index).
  - data (complex[][])
    
    Complex poles and residues. Each pole has a corresponding set of residues. For example, the i-th pole and corresponding residues are stored as
    
    The residues are in the order: scattering, absorption, fission. Complex numbers are stored by forming a type with "r" and "i" identifiers, similar to how h5py does it.
  - E_max (double)
    
    Highest energy the windowed multipole part of the library is valid for.
  - E_min (double)
    
    Lowest energy the windowed multipole part of the library is valid for.
  - spacing (double)
    
    Where is the maximum energy the windows go up to. is the minimum energy and equivalent to E_min, and is the number of windows, given by windows.
  - sqrtAWR (double)
    
    Square root of the atomic weight ratio.
  - windows (int[][])
    
    The poles to start from and end at for each window. windows[i, 0] and windows[i, 1] are, respectively, the indexes (1-based) of the first and last pole in window i.
