v1.2.0

EXPR Release v1.2.0

Values can now be compared with each other. e.g. 32 <= 50 && "foo" == "foo"

latest tag points to the latest stable release

If you want to use the project in your own cmake project, simply include expr as a subdirectory and link
with the libexpr library. The project is also tagged with release versions to be compatible with cpm,
so if your project uses that, simply include the project like so:

CPMAddPackage("gh:sillydan1/expr#latest")
