%description
We implement a cocktail algorithm, a good mixture of coordinate decent,
the majorization-minimization principle and the strong rule, for computing
the solution paths of the elastic net penalized Cox's proportional hazards
model. The package is an implementation of Yang, Y. and Zou, H. (2013)
<doi:10.4310/SII.2013.v6.n2.a1>.
