Summary:
Support custom dimensions
Had to move the definition of `Dimension` from `Duckling.Dimensions.Types` to `Duckling.Types` to avoid cyclic imports between these two modules.
A sample custom dimension is in `exe/CustomDimensionExample.hs`.
Limitations of custom dimensions:
- All rules for a custom dimension must be in the same module with the definition of the custom dimension. Otherwise there will be cyclic imports, because the definition of the dimension and the rules refer to each other.
- The custom dimension must be specified when using `parse`, since there's no way to get all the existing custom dimensions.

Summary:
Numerals that require intersection with negative numbers don't work, since the negative sign gets parsed
before the intersect rules happen. This fixes it by adding a guard in for positive in the intersection rule.

Summary:
generalize chinese digit specifier (十百千万亿) parsing, and add hanzi tests
These digits specifiers can be parsed as (<num><speci>)<num>,
by using the multiplicater value <num><speci>, and a connect function that adds them together
(two cases, skipping digits [which requires a 零 in between], and digits in consecutive locations).
Note that 个 is technically a digit specifier,
but in Chinese it is never used directly as a numeral specifier, and always as a counter.

Summary:
Before, duckling would parse `"1 2 2"` as the three digit number 122 through
`ruleSkipHundreds`. This, however, allowed the string `"Pay Kiran1 10eur"` to be
parsed as "110 EUR", which was reported in https://github.com/facebook/duckling/issues/159.
This change only accepts alphabetic numerals to pass through `ruleSkipHundreds`
(for example `"one twenty two"`), which presumably was the original intention of
this rule. This fixes the above issue, without any change in Corpus.

Summary:
When I write "dois mil e duzentos" the result should be 2200, but duckling recognize the numbers separated and give the result:
`[{"dim":"number","body":"dois","value":{"value":2,"type":"value"},"start":0,"end":4},{"dim":"number","body":"mil","value":{"value":1000,"type":"value"},"start":5,"end":8},{"dim":"time","body":"mil","value":{"values":[],"value":"1000-01-01T00:00:00.000-07:53","grain":"year","type":"value"},"start":5,"end":8},{"dim":"number","body":"duzentos","value":{"value":200,"type":"value"},"start":11,"end":19}]`
Now with this commit, duckling gives the correct result:
`[{"dim":"number","body":"dois mil e duzentos","value":{"value":2200,"type":"value"},"start":0,"end":19}]`

This adds support for greek times.
There are still some issues with expressions of the form:
```

```
Where `11:00 την πέμπτη` is parsed first (as 11:30 on Thu), instead of prioritizing `9:30 - 11:00` as the training data suggests. These tests are for the moment excluded from the corpus.

Summary:
* Locales support for the library, following `<Lang>_<Region>` with ISO 639-1 code for `<Lang>` and ISO 3166-1 alpha-2 code for `<Region>` (#33)
* `Locale` opaque type (composite of `Lang` and `Region`) with `makeLocale` smart constructor to only allow valid `(Lang, Region)` combinations
* API: `Context`'s `lang` parameter has been replaced by `locale`, with optional `Region` and backward compatibility.
* `Rules/<Lang>.hs` exposes
- `langRules`: cross-locale rules for `<Lang>`, from `<Dimension>/<Lang>/Rules.hs`
- `localeRules`: locale-specific rules, from `<Dimension>/<Lang>/<Region>/Rules.hs`
- `defaultRules`: `langRules` + specific rules from select locales to ensure backward-compatibility
* Corpus, tests & classifiers
- 1 classifier per locale, with default classifier (`<Lang>_XX`) when no locale provided (backward-compatible)
- Default classifiers are built on existing corpus
- Locale classifiers are built on
- `<Dimension>/<Lang>/Corpus.hs` exposes a common `corpus` to all locales of `<Lang>`
- `<Dimension>/<Lang>/<Region>/Corpus.hs` exposes `allExamples`: a list of examples specific to the locale (following `<Dimension>/<Lang>/<Region>/Rules.hs`).
- Locale classifiers use the language corpus extended with the locale examples as training set.
- Locale examples need to use the same `Context` (i.e. reference time) as the language corpus.
- For backward compatibility, `<Dimension>/<Lang>/Corpus.hs` can expose also `defaultCorpus`, which is `corpus` augmented with specific examples. This is controlled by `getDefaultCorpusForLang` in `Duckling.Ranking.Generate`.
- Tests run against each classifier to make sure runtime works as expected.
* MM/DD (en_US) vs DD/MM (en_GB) example to illustrate
