Small wiki documentation issues for CLI

[burgerga]

In https://github.com/auerbachs/BMDExpress-2/wiki/Command-Line#analyze:

• bm2FileName is required as well, without it you get a null error (should probably also get a more useful error message ;))
• pValueCutOff (in bmdsBestModelSelection) should be pValueCutoff (lowercase o)
• modifyFlaggedHillWtihFractionMinBMD should be modifyFlaggedHillWithFractionMinBMD (Wtih -> With)

(Also I see in the source code code for the non-parametric models in the CLI, that would be nice to add as well ;) )

Also missing in bmdsBestModelSelection: bmdlBMDUUse- Choice between (1 | 2 | 3 )

• 1 - Do not compute
• 2 - Compute and utilize in best model selection
• 3 - Compute but ignore non-convergence in best model selection

Is that about right?

Also for those interested, here an example non-parametric json config, which should be added to the top-level jsonobject:

"nonParametricConfigs": [
  {
    "@type": "gcurvep",
    "bootstraps": 1000,
    "bmrFactor": 1,
    "pValueConfidence": 0.05,
    "inputCategory": "williams"
  }
]
