ROI.plugin.coinclp 0.1.0.9000

Title and Description follow CRAN's rule that package, software and API names are written in single quotes, and only those: every quoted name is now a bare one, with no quoted function call, no acronym in parentheses and no double quotes. Requested by CRAN when 0.1.0 was accepted.

First release, reviving ROI.plugin.clp on top of the coinclp package after both it and clpAPI were archived from CRAN.
Registers Clp with ROI as the solver "coinclp", for linear objectives, linear constraints, continuous variables and variable bounds, minimising or maximising.
Returns dual values, reduced costs, row activities and the iteration count alongside the primal solution and objective value.
Accepts the control names of the earlier plugin (amount, verbosity_level, iterations, seconds) as well as coinclp's own, and adds algorithm, presolve, tolerance and scaling controls.
Handles problems the earlier plugin could not: no constraints at all, a dense constraint matrix, and an objective given as a plain numeric vector.
