/* ISO 15919 -> Devanagari -> Bengali transliteration tools

Aim: to transliterate any one of these 3 scripts into any other

ISO to indic:
1. replace ISO character blocks into conventional simbols (input:string; output:string)
2. split into single character list and revert previous replaces (input:string; output:list)
3. replace ISO characters/block with matching Devanagari/Bengali entries from JSON object (input:list; output:list)
4. combine following Indic rules (input:list; output:string)

Indic to ISO:
1. split indic string into individual characters (input:string; output:list)
2. convert indic characters into ISO characters/blocks (input:list; output: list)
3. join (input:list; output:string)

Test: Devanagari to ISO, then ISO to Devanagari, should give exactly original Devanagari text.
