--- Serialises an arbitrary value to a string.
-- Note that although the resulting table *looks* like valid Lua, it isn't.
-- Completely arbitrarily, if a table (or it's associated metatable) has the
-- key __name then it is conidered the name of the parent metatable. This can
-- be useful for identifying custom table-based types.
-- Should anyone come across a 'proper' way to obtain the name of a metatable
-- in pure vanilla Lua, I will update this to follow that standard instead.
-- @param item any Input item to serialise.
-- @param sep string key value seperator
-- @param new_line string key value pair delimiter
