    * fitModel.nls now checks whether nls with plinear option made
      a positive number of iterations (as additional convergence check).
      In some cases (eg. when number of parameters = number of 
      doses) plinear does not do any iteration and does *not* 
      put out a warning message that the algorithm failed.
    * The calcOptDesign function now allows for upper and lower bounds
      on the allocation weights.
    * There is no longer the need to specify clinRel, when one wants
      to calculate a D-optimal design.
    * Output of bootMCPMod function in case of model averaging now
      also includes dose estimates under each model & corrected
      bug in print.bootMCPMod function (thanks to Setia Pramana)

    * 1st Release as version 0.1. Improvements over MCPMod package:
      - Extended and improved version of MCPMod (allowing for covariates
        and robustified self-developed optimizer)
      - Functions for MCP (MCPtest) and Modelling (fitDRModel) part
        now available to the user
      - New functions (eg. bootMCPMod, powerScenario)
      - Functions for calculating optimal designs
