Initial change from Babel/JS to TypeScript (#70)

* will compile as typescript

* migrated test suite to use JestJS

* Migrated to Jest testing framework and typescript source files

* updated deps

* updated prepublish

* resolved 1 failing test

* changed decimal .0 on four tests, it appears that these were the only four tests expecting integer values to have '.0'

* added linter

* added package-lock

* removed tslint in favor of eslint

* changed yarn to npm

* updated version 2.6->3.0

* removing package lock

* updated node version in nvmrc and jest version in package

* removed nvmrc

* removed some unused functions

* replaced data driven with file from master

* commitint yarn.lock

* removing babel as a dependency in favor of typescript compiling to es5

* removing babel deps

* resolved testing issues by migrating helper function

* added partial linting functionality for test suite

* updated imports for decodeLedgerData

* updated test

* updated yarn.lock

* removed a console.log

* added eslint-jest-plugin to package

* reverting to old linting, will add linting in next PR

* removed comments in shamap

* re-adding .nvmrc

* npm -> yarn

* added . to .eslintrc

* added .eslintrc

* removing linting for this PR

* Changed linting to print a message so that linting doesnt fail in CI

* changing back

* added newline so diff wont show

* removed eslint deps, since linting will be dealt with in a later PR

* changed function calls to describe(...)
