Improvement to map_to_struct utility

map_to_struct now properly handles cell arrays of Maps (e.g. TOML arrayed tables).

Add utility function - map_to_struct

As requested in #20 - a library function to convert containers.Map instances into nested structs.

Support TOML 1.0

Breaking changes:

• Tables are now output as container.Map instances instead of struct
• Keys are not modified, any string is a valid key

v0.3

Breaking changes to the API:

• toml.parse is now toml.decode
• toml.load is now toml.read

New features:

• toml.encode serializes MATLAB data as TOML and returns a char.
• toml.write places this serialized output directly in a file.

Incremental updates:

• Increased (near-complete) test coverage
• More robust handling of complex TOML data

v0.2

Supports all data types in the spec, and implements error cases for invalid input.

v0.1

Each of the datatypes in the TOML spec can be parsed, and have tests to ensure no regressions occur.

Not all errors for invalid data have been implemented yet.
