minmod_model: Minimal modification of whole Boolean model
In BTR: Training and Analysing Asynchronous Boolean Models

This function generates all possible boolean models minimally modified. Returns a lists of 2 lists, deleted models and added models

1 2	minmod_model(bm, index = NULL, overlap_gene = NULL, sep_list = F, encoded = F, model_encoding, and_bool = NULL, self_loop = F)

`bm`	S4 BoolModel object.
`index`	integer. Specifying rule of which gene to modify. If NULL, modifies all rules in the model. Defaults to NULL.
`overlap_gene`	character vector. Specify which genes are present in both model and data inputs.
`sep_list`	logical. Separate add and del lists.
`encoded`	logical. Return Boolean models in encoded form to save space.
`model_encoding`	list. Only used if encoded=T.
`and_bool`	logical. Default to check_and().
`self_loop`	logical. Whether to allow self_loop in random starting model. Default to F.
