Generate a nested set of objects, given a set of rows and a set of headers.

let keys = [
    "minDistance"
    , "attractionStrength"
    , "repulsionStrength"
    , "damping"
    , "minVelocity"
    , "maxVelocity"
    , "itercount"
    , "method"
]

const confTable = new Table(keys, {
      'default': [30,  0.004, 200, 0.60,  0.1,  5]
    , 'alt':     [90,  0.002, 100, 0.66,  0.08, 5]
    , 'gas':     [100, 0.001, 800, 0.974, 0.1,  9,  1]
    , 'stable':  [100, 0.001, 80,  0.974, 0.01, 9,  1]
    , 'blob':    [90,  0.002, 100, 0.95,  0.1,  20, 1, 'springy']
})

const settings = confTable.get('blob')
{
    minDistance: 90
    , attractionStrength: 0.002
    , repulsionStrength: 100
    , damping: 0.95
    , minVelocity: 0.1
    , maxVelocity: 20
    , itercount: 1
    , method: 'springy'
}

The get method returns an object, with the keys given. If a property from the row does not exist, the keypair is not assigned to the result.

We can provide defaults for missing keys:

js confTable.get('default', { method: 'egg' })
