// Map a json struct into a simple table

/* Fields is an array, processed in order, of:
    {
        "field": "..." // Field spec
        "title": "..." // title text

        "help": "..." // Help / explanatory text

        Options will contain AT LEAST
        'key' - current field key
        'data' - current data
        'value' - resolved value
        'basekey' - string key of base in an iteration
        'base' - resolved object base
        and may also include
        'index' - iteration index
        'container' - parent container for draw functions
        'sanitize' - sanitize HTML of content, default true

        Optional function for filtering if we display this entity, returns
        boolean for display.  
        "filter": function(opts) { return bool }

        Optional shortcut filters for common filtering options
        "filterOnEmpty": boolean // Filter this row if the value does not exist,
        or exists, is a string, and is empty ('')
        "filterOnZero": boolean // Filter this row if the value does not exist,
        or exists, is a number, and is equal to 0

        Subgroups (nested table of a subset of fields)

        Indicates we have a subgroup.  Title is string, or function
        returning a string
        "groupTitle": string | function(opts)
        "fields": [...] // Additional nested fields w/in the subgroup

        Iterative groups (vectors and dictionaries of multiple values,
        the fields group is applied to each index
        "groupIterate": boolean // Do we iterate over an index of the field
        and apply fields to each?
        "iterateTitle": string|function(opts) // Fixed string
        or optional function for each index
        "fields": [...] // Additional nested fields which will be indexed 
        and grouped.

        When using iterator groups, field references should be based on the 
        inner fields, ie a top-level array field of foo.bar.array containing
        foo.bar.array[x].val1, foo.bar.array[x].val2, the sub group of 
        fields should reference fields as 'val1' and 'val2' to get automatically
        indexed by reference

        // holding js-scope variables
        "storage": {}

        // Optional string or function for rendering that should return html, taking
        // the original key, data, and resolved value; this is used to create any 
        // necessary wrapper objects.
        "render": string | function(opts) {}  

        // Optional function for drawing data, called repeatedly as data is updated; 
        // This function can return nothing and manipulate only the content it is
        // given, or it can return a string or object which replaces the current
