[FEATURE] `alias` command

[kurtlawrence]

Description

A command which can alias various things.

• alias a partitions path (eg: alias path/to/something my-path)
• alias type (alias Num N)
• alias commands (similar to path above) (alias str/regex rgx)
• alias identifiers (alias "Some complicated column header" h1)
  • extend this to any literal? (alias 3.14 pi)

As a pre-processor?

Since there is not any runtime evaluation that would be required, would this be done as a preprocessing step?

• Think about the overwriting of aliases
