How to use

Probably the best way to get started is to look at the examples, starting with examples/minimal.rs.

Most relevant modules

• prelude exports a list of the most relevant classes and objects
• cres contains the main class and lists the steps that are performed
• io event input and output (from and to files)
• event for the internal event format
• distance for user-defined distance functions
• seeds and resampler for the resampling
