Description

For example, if I import a function as follows:

math.import({
  area: function (x, y) {
    return x*y
  }
})

I would like to then define a help object for this new function so I can call math.help("area"). Is this possible?

Contributor guide

Research direction
Investigate the existing help system in mathjs. Look for how built in help objects are defined and registered. Then propose a way to allow users to define custom help objects via a new API method (e.g., math.defineHelp) or by extending the import mechanism to include help property. Check if there is an existing internal registry for help objects. The goal is to make math.help('area') work for user defined functions.
