We do not return old style bool on error, we throw Exceptions: HtmlBuilderExcpetion
Element has more classes to set tag, id, etc with basic checks for valid data
String Replace to set strings is one array with key -> value entries
Errors thrown on index for element/replace blocks
Object build is a replicata from the JS one
Array is similar but build on pure Array elements
String replace is just a simple string replacer for now
General\Error for overall error handling
General\Settings for Object/Array based checks and settings
