Custom build tool

[panzerdp]

Voca library needs a custom build tool to generate configured builds.

Rough the command npm run build should implement the following settings:

• Accept the list of functions that must be included,
  e.g. --functions sprintf,camelCase,insert,latinise
• Accept the list of function categories that must be included,
  e.g. --categories escape,format
• Accept the list of functions that must be excluded (used in combination with categories),
  e.g.--exclude-functions insert,latinise
• Accept an exported format cjs (CommonJS), umd (Universal Module Definition), iife, es,
  e.g. --format cjs
• Accept a minification parameter,
  e.g. --minify
• Accept a FP build parameter:
  e.g. --fp
• Accept an output file path parameter:
  e.g. --output dist/voca.cust.build.js

For instance the following command creates a fp build exported as CommonJS of sprintf() and latinise() functions:

npm run build --functions sprintf,latinise --format cjs --fp

Decided for now to delay the implementation. May be reopened in case of necessity.
