Added isEQ, isLT, isLE, isGT, isGE functions for dvectors. Revised output from array-specific  rFunctions to incorporate dimension names, as well as dimension indices.
Changes include isEQ(...) and related functions for comparing dvectors to doubles. Also modified R functions to incorporate dimension names (as well as values) for arrays. Also incorporated a modified rmvlogistic(...) function based on the ADMB version.
