// Takes a row as input and produces an alternate view of the row based on

// every column of a particular family, give just the two most recent cells
// which are older than timestamp X."
//
// There are two broad categories of RowFilters (true filters and transformers),
// as well as two ways to compose simple filters into more complex ones
// (chains and interleaves). They work as follows:
//
// * True filters alter the input row by excluding some of its cells wholesale
// from the output row. An example of a true filter is the `value_regex_filter`,
// which excludes cells whose values don't match the specified pattern. All
// regex true filters use RE2 syntax (https://github.com/google/re2/wiki/Syntax)
// in raw byte mode (RE2::Latin1), and are evaluated as full matches. An
// important point to keep in mind is that `RE2(.)` is equivalent by default to
// `RE2([^\n])`, meaning that it does not match newlines. When attempting to
// match an arbitrary byte, you should therefore use the escape sequence `\C`,
// which may need to be further escaped as `\\C` in your client language.
//
// * Transformers alter the input row by changing the values of some of its
// cells in the output, without excluding them completely. Currently, the only
// supported transformer is the `strip_value_transformer`, which replaces every
// cell's value with the empty string.
//
// * Chains and interleaves are described in more detail in the
// RowFilter.Chain and RowFilter.Interleave documentation.

// exceed 4096 bytes, and RowFilters may not be nested within each other
