This package contains the following modules:

1. Classical entropy functions: These functions are ideal for calculating the classical spectral entropy and entropy similarity for a small set of spectrum pairs.

2. Flash Entropy Search Algorithm Functions: If your task involves searching spectra against a large spectral library, this algorithm will significantly improve the speed of the search process.
