[aryang13]

Acceptance Criteria

• add all different handling of getUsers listed in the title
• add paramters properly to the URL (e.g. use search query parameters)
• add the middleware function to call

new LambdaBuilder(router)
    .use(new PaginationHelper({ limit: DEFAULT_LIMIT, offset: DEFAULT_OFFSET}))
    .build();

Development tasks

• work on paging similar to how it is set up in src/standings/getStandings.ts
• searching
  • do research on what is the best way to do this
  • maybe just using DB call LIKE or using index searching
• add filtering on different values

Learning Opportunities

• adding on top of pre-built HTTP Methods
