Possible questions

• Why have you modified buildFeatureFilter fn?
  It's a minor improvement to avoid calling Object.keys for each feature

• Why that new applyFilters fn in core?
  I think this can be used in advanced use cases.

• Do you think that sorting might be part of core?
  I don't think so because it's just used in workers, and I don't think it can be used in other parts of C4R or even that C4R have to provide any kind of sorting out of the main think. Idk. Let me know what do you think.

• What's sortBy structure?
  This can be checked here.
  sortBy accepts:

  1. An string (a column) sortBy: 'column_1'
  2. Array of strings (multiple columns) sortBy: ['column_1', 'column_2']
  3. An array where each element follows thenBy structure. Passing each child array as arguments to firstBy/thenBy functions. Thank to this we are able to specify direction for each column or ignoring cases or any other feature of thenBy.

Example of the third option:

sortBy: [
    ['column_1', 'desc'],
    ['column_2', { direction: 'asc', ignoreCase:true }]
]

• I saw that thenBy accepts function? Does sortBy accepts function?
  Nope, functions cannot be cloned to workers.

• If I indicate direction using thenBy structure and I also indicate sortByDirection. Which is applied?
  thenBy structure has priority since it's more specific. If sorting is applied by multiple column and some doesn't indicate direction, sortByDirection is used (which value by default is 'asc').
