type PaginationRepo

type PaginationRepo struct {
	Offset int
	Limit  int
}

PaginationRepo is used as pagination when listing data Why using lastID instead of offset? Because in mysql, using limit X, Y will read X + Y rows, instead of only Y rows. Mysql reads all X + Y rows, then drop rows before X. Read this for more explanation: https://stackoverflow.com/questions/3799193/mysql-data-best-way-to-implement-paging#comment4027585_3799223
