// /mINI/ v0.9.10
// An INI file reader and writer for the modern age.
//
///////////////////////////////////////////////////////////////////////////////
//
// A tiny utility library for manipulating INI files with a straightforward
// API and a minimal footprint. It conforms to the (somewhat) standard INI
// format - sections and keys are case insensitive and all leading and
// trailing whitespace is ignored. Comments are lines that begin with a
// semicolon. Trailing comments are allowed on section lines.
//
// Files are read on demand, upon which data is kept in memory and the file
// is closed. This utility supports lazy writing, which only writes changes
// and updates to a file and preserves custom formatting and comments. A lazy
// write invoked by a write() call will read the output file, find what
// changes have been made and update the file accordingly. If you only need to
// generate files, use generate() instead. Section and key order is preserved
// on read, write and insert.
//
///////////////////////////////////////////////////////////////////////////////
//
// /* BASIC USAGE EXAMPLE: */
//
// /* read from file */
// mINI::INIFile file("myfile.ini");
// mINI::INIStructure ini;
// file.read(ini);
//
// /* read value; gets a reference to actual value in the structure.
// if key or section don't exist, a new empty value will be created */
// std::string& value = ini["section"]["key"];
//
// /* read value safely; gets a copy of value in the structure.
// does not alter the structure */
// std::string value = ini.get("section").get("key");
//
// /* set or update values */
// ini["section"]["key"] = "value";
//
// /* set multiple values */
// ini["section2"].set({
// {"key1", "value1"},
// {"key2", "value2"}
// });
//
// /* write updates back to file, preserving comments and formatting */
// file.write(ini);
//
// /* or generate a file (overwrites the original) */
// file.generate(ini);
//
