setar: add coef method, whit argument hyperCo=TRUE
NMSP: export coef.setar
tests: add coef() hyperCo=FALSE in tests
lstar: add new coef(), with hyperCo=TRUE
tests: lstar: add test on coef(hyperCo=FALSE), add more systematic tests on AIC, BIC, etc
Test setar: use of list for all setar models, systematic call of sapply for AIC, BIC, resid etc... add also on x
setar: name column in x, update tests
test setar: add test on summary
setar: small modf in code, using now coef(hyperCo)
lstar: return  with coef names
lstar: rename coef names, putting L/H instead of 1/2, update test outputs
setar: change coef names, substitute space in const L/H by dot, as const.L/H
test seatr: add model with include = trend, both, none
tests setar: add test for toLatex, but only for 3 models
setar: show in print output const/trend first, simplify the getSetarXRegimeCoefs function, update the 00seta test
