Codebase release 1.0 for Kolya

We introduce the code kolya, an open-source tool for phenomenological analyses of inclusive semileptonic B\to X_c l\bar \nu_l <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:mi>B</mml:mi><mml:mo>→</mml:mo><mml:msub><mml:mi>X</mml:mi><mml:mi>c</mml:mi></mml:msub><mml:mi>l</mml:mi><mml:msub><mml:mover><mml:mi>ν</mml:mi><mml:mo accent="true">‾</mml:mo></mml:mover><mml:mi>l</mml:mi></mml:msub></mml:mrow></mml:math> decays. It contains a library to compute predictions for the total rate and various kinematic moments within the framework of the heavy quark expansion, utilizing the so-called kinetic scheme. The library currently includes power corrections up to 1/m_b^5 <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:mn>1</mml:mn><mml:mi>/</mml:mi><mml:msubsup><mml:mi>m</mml:mi><mml:mi>b</mml:mi><mml:mn>5</mml:mn></mml:msubsup></mml:mrow></mml:math> . All available QCD perturbative corrections are implemented via interpolation grids for fast numerical evaluation. We also include effects from new physics parameterized as Wilson coefficients of dimension-six operators in the weak effective theory below the electroweak scale. The library is interfaced to CRunDec for easy evaluation of the quark masses and strong coupling constant at different renormalization scales. The library is developed in Python and does not require compilation. The code is flexible and can be extended to other kinds of inclusive decays such as B <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>B</mml:mi></mml:math> meson lifetimes, B \to X_u l\bar \nu_l <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:mi>B</mml:mi><mml:mo>→</mml:mo><mml:msub><mml:mi>X</mml:mi><mml:mi>u</mml:mi></mml:msub><mml:mi>l</mml:mi><mml:msub><mml:mover><mml:mi>ν</mml:mi><mml:mo accent="true">‾</mml:mo></mml:mover><mml:mi>l</mml:mi></mml:msub></mml:mrow></mml:math> and D <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>D</mml:mi></mml:math> meson decays.
