## Which issue does this PR close? Part of #7013 ## Rationale for this change I was working on another example, and I wanted to create a `PhysicalExpr` but could not figure out how to do so easily from the docs (I had to go poking around in the code) Thus I wanted to provide improved documentation for myself (and I suspect others) ## What changes are included in this PR? 1. Improved documentation on `PhysicalExpr ` 2. Examples of how to create a `PhysicalExpr` and how to execute it <!-- There is no need to duplicate the description in the issue here but it is sometimes worth providing a summary of the individual changes in this PR. --> ## Are these changes tested? <!-- We typically require tests for all PRs in order to: 1.
