check whether it works for solvers apart from squared, logistic
Could you please check C++ part - especially headers and macros which I defined to use R's stdout, stderr management (this is CRAN requirement - R pkg should not touch C stdout/stderr and use R's API for that).
NOTE that RcppExports.R and RcppExports.cpp are auto-generated files, no need to check them (not sure how are you familiar with R, so want to make sure you won't have extra work trying to understand them).
Related to #1. Not ready for merge yet:
