 * vcfGenotypeLookup() : preArgs : {... , requestInfo: 'false', requestFormat: 'Numerical', requestSamplesAll: 'true', snpPolymorphismFilter: 'false'}
 * Parse these to convert to native boolean values true, false.

 * Use this also for numeric values - JSON.parse() works for those also, e.g.
 * Block.blockFeaturesCounts : userOptions : { ... mafThreshold : '0', ... }
