why this folder is here as its own folder

problem:

• naming and file count for validator + schema was becoming bad
• too many 'factories'
• logic for core was in deps where it should not be
• method chain was too big
• file size was too big
• external configuration was not so easy solution:
• move all domain logic related to methodchain out of deps
• plugins for method chain

example

// @NOTE isNull & isUndefined to lowercase is no good...
//       one way to do it, but not as good
// const TYPES = ['null', 'undefined']
// const REPLACE = ['nill', 'undef']
// .replace(TYPES[0], REPLACE[0])
// .replace(TYPES[1], REPLACE[1])
//
// @NOTE: removed this in favor of escaping the key
//        plus this 2x the map size
//
// const ObjectKeys = require('chaintools/util/keys')
// const validationKeys = ObjectKeys(is)
// for (let i = 0; i < validationKeys.length; i++) {
//   const key = validationKeys[i]
//   const transformedKey = key.toLowerCase().replace('is', '')
//   is[transformedKey] = is[key]
// }

// s.charAt(0).toUpperCase()
