Directdm

Changed
- `USAGE.md`: Clarification that numerical inputs of Wilson coefficients should explicitly include the scale.

Fixed
- Corrected typos in `USAGE.md`
- Errors in QCD anomalous dimension

Added
- Hisano's fermionic twist-two contributions from [this publication](https://arxiv.org/abs/1104.0228)

Changed
- Input parameters are now given in form of a dictionary that can easily be updated by user-defined input values

Fixed
- Corrected typos in `USAGE.md`
- Corrected typo in FGtilde form factor

Added
- Running routines for quark masses
- Added module `dm_eft.py` containing "wrapper" classes that provide user-updated input to Wilson coefficient classes.
- Updated `USAGE.md`

Added
- File `USAGE.md` with basic explanation of relevant classes

Changed
- Initial conditions of Wilson coefficients above the weak scale require scale explicitly
- Method `run` of class `WC_EW` requires scale `mu_Lambda` as starting value for RG evolution
- Updated `example.py`
- Updated `README.md`

Fixed
- Typos in `rge.py`
- Typos in `example.py`

Added
- The class `WC_EW` for the Wilson coefficients above the electroweak scale.
It performs the running above the weak scale, and matching to the five-flavor EFT,
as detailed in [this publication](https://arxiv.org/abs/1809.03506)
- The class `CmuEW` for the electroweak RG evolution
- The files `full_adm_g1.py`, `full_adm_g2.py`, `full_adm_yc.py`, `full_adm_ytau.py`,
`full_adm_yb.py`, `full_adm_yt.py` with the electroweak anomalous dimensions
- The file `dim4_gauge_contribution.py` with the electroweak matching contributions from [Hisano et al.](https://arxiv.org/abs/1104.0228)

Changed
- Numerical input from PDG 2018
- Running of strong coupling (consistent decoupling at flavor thresholds)
- example.py includes an example for Wilson coefficients specified in electroweak unbroken theory

Fixed
- Bug in running of the strong coupling constant (decoupling at wrong loop order)

Fixed
- Typos in README
- Bug in matching methods (wrong order of optional arguments)

Added
- Uploaded package to the [Python Package Index](https://pypi.org/)
