* added _safeTransferFrom function * added safeMint functions * added package-lock.json for consistency, don't know why it changes * added initial suggestions/modifications * change _safeTransferFrom to internal, reverted package-lock.json to original, and changed ERC721Pausable to override _transferFrom instead of transferFrom * included tests for safeMint functions * modified safeMint tests to be on ERC721Mock contract * added safeMint to ERC721Mintable & respective test to ERC721MintBurn.behavior.js
