 Motif scanning with position weight matrices (also known as position-specific 
 scoring matrices) is a robust method for identifying motifs of fixed length
 inside a biological sequence. They can be used to identify transcription

 The `lightmotif` library provides a Rust crate to run very efficient 
 searches for a motif encoded in a position weight matrix. The position
