Slightly more in-depth:
Using the file commands requires a pre-opened ifstream or ofstream object (depending if you are reading or writing). Passing a stream that doesn't have an open file will not the application to crash, but nothing will happen.
Banks are blocks of memory that are allocated to your application. You can allocate any number of blocks as long as the total system memory isn't exceeded. Reading or writing outside of the range does not cause the application to crash, but nothing will happen. You might want to use these, if for example, you want to extract some data out of a custom package file, and don't want to extract it to disk, read it with your application, and then delete it again.
The number returned is the address in memory, but it's not a pointer type, so you can put an address of one bank into another one, and create a list of variables. The addresses are presented as 64-bit, but as it's not compiled on a 64-bit system, you'll only be able to use up to 4GB. Assuming you've got that much going spare anyway. 64-bit is used now so when it is compiled for 64-bit, anyone using this doesn't have to re-write these bits of code to reflect the change.
The Ticker can only calculate the number of expected ticks if you tell it what the current time is. If you're using tickers, make sure you call the static UpdateTime method. You can either pass in the time yourself, or let the ticker obtain its own time.
You might want to use a ticker to limit playback to just 30 fps. I can't think why anyone would do that, but it's possible. Alternatively they can be used in FPS games to control how fast a weapon fires. If the application slows down for a moment, the ticker will inform you of how many shots were missed due to the lag.
String helpers are probably going to be the least useful part of the lib. They look at strings and retrieve individual words, substitute words (Could be combined for a little kids swearing filter). Strings can have a certain character trimmed from the start, and the end of a string.
The only useful part of the string helpers is being able to convert numbers to strings, and vice versa.
Anyone thinking it might be useful, and wanting examples, just ask...
