Data Serializer and Logger

[cowsed]

Fair warning, I don't know if this works because I do not have a brain (it builds tho).

Serializer

Usage:

Serializer s; // create an empty serializer

s.set_bool("do_stuff", true);
s.set_double("voltage", 11.54);
s.set_int("auto_program", 12);
s.set_string("name", "Flynn");

s.save_to_disk("out.txt"); // Save to disk. If this is not called, nothing will be saved

Serializer s2("out.txt"); // load data from out.txt
s2.bool_or("do_stuff", false); // retrieve 'do_stuff' or false if 'do_stuff' is not specified
s2.double_or("voltage", 0.0); // retrieve 'voltage or 0.0 if 'voltage' is not specified
s2.int_or("auto_program", 1); // retrieve 'auto_program' or 1 if 'auto_program is not specified
s2.string_or("name", "No Name");  // retrieve 'name or No Name if 'name is not specified

Logger

    Logger l("log.txt"); // Will automatically write to "log.txt"

    // "Bare" logging
    l.Log("Text with manual newline\n");
    l.Logln("Text with automatic newline");
    l.Logf("Formatted %s %c", "Text", '!');


    // Tagged logging (DEBUG, NOTICE, WARNING, ERROR, CRITICAL)
    l.Log(LogLevel::WARNING, "Text with manual newline\n");
    l.Logln(LogLevel::ERROR, "Text with automatic newline");
    l.Logf(LogLevel::DEBUG, "Formatted %s %c", "Text", '!');

Open Questions:

• Should logger include timestamps
• Should all log lines have a level or should no log lines have a level.
• Will this be performant enough (VEX Sd card functions are wild, maybe we should add some buffering inside Logger and also have Logger.flush(); which will then do the actual saving)
