add special LP constraints to an existing LP object–pair overlap control

addon_blockSolution(
  lp_obj,
  whichSolution = NULL,
  block_within_forms = T,
  block_across_forms = F,
  maxOverlapRate = 0.8,
  assignSolutionWtZero = T
)

`lp_obj`	the LP object that has been solved at least one time
`whichSolution`	whichSolutiion in the lp_obj$formList should be added as a constraint controlling the overlap rate between this solution and those being generated iteratively.
`block_within_forms`	if TRUE, the overlap rate control per form is added as new constraints.
`block_across_forms`	if TRUE, the overlap rate control across forms is added as a new constraint. block_within_forms and block_across_forms can both be TRUE.
`maxOverlapRate`	the maximum overlap rate between the next new solution and the previous solutions.
`assignSolutionWtZero`	assign the solution items to have objective coef to be zeros.
