      We need some way to represent a histogram of values in the field, as those will be useful. However, we can't count on being able to hold such histograms in memory. Have to figure out how they can be kept on disk and represented here. for now.. don't create so many buckets you can't hold them in memory an ordered array of the most common values, in descending order of frequency
    - mostCommonValuesFreq
```
float[] mostCommonValuesFreq
```
      an array that matches the mostCommonValues array, and lists the frequencies of those values as a fraction (0 through 1) of the total number of records
    - valueHistogram
```
Object[] valueHistogram
```
      an ordered array of values, from min val to max val such that the number of records with values between valueHistogram[i] and and valueHistogram[i+1] is roughly equal for all values of i. NOTE: if mostCommonValues is non-empty, the values in that array should not be included in the histogram. Adjust accordingly.
