v1.0.4: Bugfix to v0.1.3

Resolve a bug that let the compilation fails.

Update:
Note that this release has a wrong version number. It should be v0.1.4. But since a PR has already been made. So I am not going to change it.

Rename package to EquationsOfState.jl

Based on this request

v0.1.2

Update version number in Project.toml
