Here are the code samples of the Tiltmeters application.

- File T1_01 is a sample data file

Basically, Tiltmeters uses the following classes:
- MainToolBar	(main.*)
  This class is the main application class. It initializes
  all the charts, the variables, and sets up the options
  by reading the configuration from the registry.
  It also prepares the data files and check for new
  values. Once done, it tells the charts to show up.
  Of course it also responds to all the user actions on
  the dedicated toolbar (arranging charts, editing data,...)

- ChartForm	(chart.*)
  This class is used to display each chart. The chart itself
  knows how to draw the graph, and it actually handles 
  everything related to the formula parsing.
  Each chart knows what to draw and which data to use along
  with which formula.
  It also receives messages from MainToolBar when it has to
  update its content (for new incoming data).

- Configure	(config.*)
  This class handles everything related to the access in
  read or write mode to the registry. All settings and options
  are managed in this class.

- Search	(searchfile.*)
  This class is run once at the beginning. It scans all the files
  and looks for new data since the latest session.
  It also starts reading the data from the day after "today" up
  to today (in this particular case, we have a 1 year roll-over 
  data cycle as we never need more than 1 year worth of data).
  The result is one file full of cleaned data per data recorder.
