create a package structure for Rcpp and RcppArmadillo
changed first dev for multigroup
d, starts with 0 and is list(matrix)
sim and control
reshape returns slightly different informations
embed C++ function
changed derivs to new input type
C++ things
1st, 2nd derivs - input and arguments adapted
d1uc new in reshMG (nrm)
mue_nrmC --> nrm mean/sd/SE estimation in c++
changed to c++ estimation.
data preperation is still done in native R
d1uc is used instead of recm - because NAs are not needed for expected value estimation
changed ZF
EAP estimation for nrm is now performed in mueNRM
deleted control for minimum category
Rcpp things
#1) If there is more than 1 group, then from the 2nd to the last EM Iteration, Enrm solely forwards the mueNRM estimation for riq and fiq
#2) quadIT nonparametric estimation --> object name has changed
default number of quadrature nodes is now 21 due to the faster estimation procedure
updated README
version update
colSums replaced by rowSums for nonparameteric estimation.
reshMG - killed the nelm specific reshape part
