## This module implements a mimetypes database

runnableExamples:
  var m = newMimetypes()
  doAssert m.getMimetype("mp4") == "video/mp4"
  doAssert m.getExt("text/html") == "html"
  ## Values can be uppercase too.
  doAssert m.getMimetype("MP4") == "video/mp4"
  doAssert m.getExt("TEXT/HTML") == "html"
  ## If values are invalid then `default` is returned.
  doAssert m.getMimetype("INVALID") == "text/plain"
  doAssert m.getExt("INVALID/NONEXISTENT") == "txt"
  doAssert m.getMimetype("") == "text/plain"
  doAssert m.getExt("") == "txt"
  ## Register new Mimetypes.
  m.register(ext = "fakext", mimetype = "text/fakelang")
  doAssert m.getMimetype("fakext") == "text/fakelang"
  doAssert m.getMimetype("FaKeXT") == "text/fakelang"
