	- [x] Change '+'/'-' to enum
	- [x] Inserting a value insert's its key in it's parent's children 
	- [x] Re-implement get_array_table_key to take into account implicit tables are always standard tables

* ast/structs.rs
	- [x] Re-implement HashValue to have a list of children or max index of children

	- [x] Change '+'/'-' to enum

* objects.rs
	- [x] In array_table when adding to existing table get_key_parent and add the new index as a child in the map, then add full_key to the map with None value
	- [x] Fix add_implicit_tables
	- [x] In array_table if table keys imply subtables that don't exist, add the implied tables as std_tables to the map with None value and add add their subkeys as children (partially done)
	- [x] In std_table if table keys imply subtables that don't exist, add the implied tables as std_tables to the map with None value and add add their subkeys as children
	- [x] In array_table if get_key_parent exists and has no indexed children, then it is an error (see toml-test/invalid/table_array_implicit)
	- [x] In array_table when encountering a new table that isn't a subtable of the last table, rebuild last_array_tables and last_array_tables_index by starting at the first subkey, looking up it's children and so-on, if the array_table already exists
	- [x] In array_table always add new table to map with None value
	- [x] In std_table always add new table to map with None value
	- [x] In array_value insert_key_val_into_map

* parser.rs

    - [x] Implement inserting new Array or InlineTable value into AST
	- [x] Implement ~~get_errors~~ Errors are returned as part of pars result if there are any
  - [x] TOMLValue parsing on set_value (currently set_value accepts whatever you give it). *In progress, almost finished*
	- [x] Implement get_children
