before mar 2 doesn't work

[bcowgill]

before march 2 start: 2017-3-2-12-0-0 end: undefined

would expect start to be timestamp 0 or be able to configure a value for earliest date we can search.

before x sounds very ambiguous to me... it could be any value that is < x. The value that is parsed here is march 2.

> c.parse('before march 2')
[ ParsedResult {
    ref: 2017-07-03T20:06:11.442Z,
    index: 7,
    text: 'march 2',
    tags: { ENMonthNameMiddleEndianParser: true },
    start: ParsedComponents { knownValues: [Object], impliedValues: [Object] } } ]

If before X is confusing, we could go with upto:
Ex: upto 2 weeks ago, upto a month ago

A hack to achieve this is to say from Jan 1, 1970 to 2 weeks ago (from epoch), but it's an ugly hack and a lot of the time is not what we are looking for anyway, since we might want to dynamically resolve start date.

The idea here is for result.start.date() to be undefined, and only for result.end.date() to be resolved. Hope that makes sense...
