MMGS v1.0.0

The first stable version of the installation package can be used for cross-validation in multiple environments. Users can use different classical Genomic Selection models for their own analyses according to the Norm reaction principle or the GxE principle. Since this is the first version, there are still many latent problems, and there may be some bugs in the code construction process for the function function calls or the use of global variables.
Users are welcome to point out. We will update it regularly.
