cmdstan installation

Minimal requirement

Note: CmdStan.jl and CmdStan refer to this Julia package. The executable C++ program is 'cmdstan'.

To run this version of the CmdStan.jl package on your local machine, it assumes that the cmdstan executable is properly installed.

In order for CmdStan.jl to find the cmdstan you need to set the environment variable JULIA_CMDSTAN_HOME to point to the cmdstan directory, e.g. add

export JULIA_CMDSTAN_HOME=/Users/rob/Projects/Stan/cmdstan
launchctl setenv JULIA_CMDSTAN_HOME /Users/rob/Projects/Stan/cmdstan

to ~/.bash_profile or add ENV["JULIA_CMDSTAN_HOME"]="./cmdstan" to ./julia/etc/startup.jl.

I typically prefer cmdstan not to include the cmdstan version number so no update is needed when cmdstan is updated.
