do not limit readhandlers to js / make it public

[hans-d]

See:

• https://github.com/krakenjs/swaggerize-builder/blob/master/lib/readhandlers.js#L26
• https://github.com/krakenjs/swaggerize-builder/blob/master/lib/readhandlers.js#L29

These limit the require to only js files.
Would be nice if, eg via an optional parameter, also other files could be included, eg coffee (only make extension configurable, being able to use coffee should be done outside this lib)

Perhaps even better if also the function could be made public, so that it could be used in construction of the handler object. Eg to do

swaggerize = require 'swaggerize-express'
builder = require 'swaggerize-builder'
yaml = require 'js-yaml'
fs = require 'fs'
_ = require 'lodash'

readApi = (file) ->
    raw = fs.readFileSync file
    yaml.safeLoad raw

buildHandler = (dir) ->
    _.merge {}, [
        builder.constructHandler dir, 'js'
        builder.constructHandler dir, 'coffee'
    ]

module.exports = (options) ->
    swaggerize
        api: readApi options.spec
        docspath: options.docUrl
        handlers: buildHandlers './controllers'

Fair enough.
